That's not true. You can have true random numbers without duplicates. Each successive iteration of the function just has to take place over a set that does not include the values chosen previously. Redefining the set your function acts on each iteration is most certainly mathematically valid. Now generating true randomness, well, that's a much more difficult topic.
