That's the case with any gambling though, some people will make a ridiculous profit but most will lose. Sure, that guy might have made 1 B, but other players probably lost more than that combined from it. There's really no point playing Routlette if the payout for a single number is 12 to 1, you're practically guaranteed to lose money no matter what you do. The house always has a statistical advantage with Roulette, there's no need to rig it further.
