Hi there Domas,
I believe nothing is impossible and anything is possible if you personally absolutely believe it yourself. I have no personal experience with winning the lottery although I do know a couple of people who have won (not through visualisation) and it has brought some problems including initial bouts of depression for one in particular.
Personally, I think what you would do if you aquired a large amount of money would be much more of a driving force. The "why" is the thing that matters the most. Here are a couple of pieces I have copied from other threads I posted a few years ago from one of my journals. I hope you find them helpful

They certainly have worked amazingly for me:-
The following major lesson I learned from Jim Rohn:-
Make a list of 50 things that you would like to achieve or have in the next ten years - big things - little things, it doesn't matter. Write at least 50 and only write one thing on each line because you will need space to write something else a little later.
These are not things that you think you can aquire - it's a list of what you want - just let your mind run free. What would make your life dazzlingly unique?
What places would you like to visit?
Would you like to write a book, create a song, learn to play a musical instrument?
Expand your library
Investments you'd like to make
Education for your children
What would do it for you?
Parachute out of an aeroplane or bunji jump
Climb a mountain
Life is a collection of experiences. What would give you great satisfaction?
Maybe some benevolence goals - become a benefactor
Set up a youth camp or an orphanage
What would reward you - give you that wonderful feeling that you have contributed and helped?
Be a teacher, speaker, lecturer, author, poet, singer. One of the greatest forces that stir the human soul are music, lyrics and poetry.
Debt free
They don't have to be big things.
Something that you've got to prove to yourself
Something that would give you great satisfaction
Entrepeneur
Executive
This is a model that you can use and then teach. You can teach this to your children and they will have no problem with this - they would probably already be asking for more paper
If you could have everything you wanted to make your life just how you would like it to be, what would you write. I realized I had forgotten how to use my imagination.
I asked "What will make me kind, rich, effective, live an extraordinary life?"
When you have listed at least 50, look at each item and decide that one is about a 1 year goal, that is about a 3 year goal and that one is a 10 plus year goal. Mark each one with the appropriate number of 1, 3, 5 or 10.
If you've not done this before you could be astounded. I hadn't thought so much about this goal setting ever in my life - planning my future.
Now, look at all the 1 year goals, pick out the 4 most important and put them on a new list. One of the greatest exercises in life is deciding what's important and what isn't. Don't spend major time on minor things. Save your energy for the majors.
Now ask yourself why these 4 goals are important to you. It's the why that makes the difference. If the why isn't important enough to you then don't waste your time on it.
What you want is the object - it's powerful - it's like a magnet.
Why you want it is the purpose. Purpose stirs the emotion and the passion.
PURPOSE IS STRONGER THAN OBJECT.
For example:- You want a 4 wheel drive because you like the look of them.
Or, the purpose of you wanting a 4 wheel drive is because you and your family travel along rough terrain each day and often get stuck if it's muddy.
The purpose of why you want the 4 wheel drive has a much stronger pull for you than the want because you will eliminate this particular challenge for you and your family.
So the two important questions are what do you want and what do you want it for.
A lot of your goals need to be personal development goals to help you become the person you want to become.
Beware of what you become in pursuit of what you want.
It's incredible what you can become.
Jim Rohn's mentor suggested to him while they were discussing economics, "Why don't you set a goal to become a millionaire for what it will make of you to achieve it. Once you have become a millionaire, the money will not really be of importance - you can give it away - the real value is what you have learned and who you have become"
You will have learned to solve problems, improvise, gain an understanding of the market place, be more knowledgable and bring value to the market place
This philosophy changed his life.
That's the positive side and in life there is always a positive and a negative.
The creator and the spoiler
Day and night
Health and illness
Winning and losing
Life and death
Liberty and tyranny
We must see the opportunities and sense the dangers.
Whatever you want will come with a cost.
If it costs you working hard, discipline and learning some skills, that's good.
If it costs you violating your values and principals the cost is too high - nothing is worth this.
Don't compromise good friendships for something that has you driven too much.
Weigh up the cost first - don't look back and realize that this has cost too much. If it costs you to be disloyal then it's not worth it.
Judas got the money - a small fortune at the time - was this a success story? No it wasn't. Why? because he wasn't happy with himself. He had got his hot little hands on the money but he wasn't happy with himself because he had sold out. He tried to take the money back but they just through him out and he hanged his worthless self because of the betrayer he had become.
The only added advice I would give is play Creative Flow if you choose to do this exercise. I wish you an abundance of peace, joy and wonderful experiences
The Power of Habit
________________________________________
The Power of Habit by Dr. Denis Waitley
"You may know me.
I'm your constant companion.
I'm your greatest helper; I'm your heaviest burden.
I will push you onward or drag you down to failure.
I am at your command.
Half the tasks you do might as well be turned over to me. I'm able to do them quickly, and I'm able to do them the same every time,
if that's what you want.
I'm easily managed; all you've got to do is be firm with me.
Show me exactly how you want it done; after a few lessons I'll do it automatically.
I am the servant of all great men and women; of course,
I'm the servant of all the failures as well.
I've made all the winners who have ever lived.
And, I've made all the losers too.
But I work with all the precision of a marvelous computer
with the intelligence of a human being.
You may run me for profit, or you may run me to ruin;
it makes no difference to me.
Take me. Be easy with me, and I will destroy you.
Be firm with me, and I'll put the world at your feet.
Who am I?
I'm Habit!
Habits are replaced, not broken. Habits are like submarines. They run silent and deep. Habits grow by observation, imitation and repetition from cobwebs into cables to strengthen or shackle our lives. First we make our habits, then our habits make us.
Success and failure are both habit-forming. Find mentors and role models with proven track records of success and emulate them."
We often form habits that take care of the way we look on the outside yet we often fail to form the habit of looking inward to take care of what matters most.
Creating the regular habit of meditation allows the harmful habits to be released allowing us to become familiar with a new and healthier way of being.
Domas, the truth is, many people will read the above, think it's great advice and then never get around to doing it. If you make the time to do it, I would love to hear the differences it makes to your life.
Who you become along the way is invaluable and once you have succeeded, you'll know you can do it again and again. I hope this helps and wish you an abundance of peace, joy and success
