What does "However, you can pick the same number twice or even three times and there is also a much 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.
