Randomness is about having a uniform probability of results, but that does not translate into a uniform distribution of results, nor can it, because of the de-correlation between random results. Specifically, the chance of getting the same result multiple times is non-zero, and actually can be fairly high with a lot of samples, whereas the chance of duplicate results in a uniform distribution is zero.
