What does "However, you can pick the same number twice or even three times and there is also amuch higher chance that 10 of the 100 numbers will come up." mean? How many multiples of numbers are there? Are the numbers 1 through 10? Is one number represented more than the others. These questions affect the probability of someone winning.

From your description, it sounds like 10 of the balls has a higher chance of being selected than the other balls. You would need to know WHAT the probability of selecting those balls are to give an accurate probability of success.
