1. He has the right to keep the money (he won the lottery prize legitimately).
2. He gets sent to jail or faces some other legal consequences for violating the terms of his parole.
I don't see how the terms of his parole have anything to do with what happened subsequently as a result of his violation of those terms (since there was nothing inherently illegal about winning the lottery in and of itself).

Ding Ding Ding. We have the winner. Unless the terms of his parole say that he must surrender any winnings or the rules of the lottery state that persons restricted from legally playing the lottery are ineligible then the money is his and his punishment should be the same as it would have been had he not won.
