Some rules in ToS won’t hold up in court. A few bets from the UK will not invalidate $64k winnings.
That's just the thing: we have no way of knowing that. All we have is our gut feeling whether or not OP is telling the truth. Only he knows if he is being honest or not. And if he is absolutely certain in his innocence, then it makes sense going down the road of a lawsuit.

Have you given any thought about what I said regarding GSM triangulation to try and prove the locations where you were physically when you accessed and played at Rollbit? Check with your data providers to see what they say on that subject and do some google searching.
My thinking is even if a court deemed that some plays came from the UK, only those bets would be cancelled. The others bets would stand. The way Rollbit wants to apply their ToS, if one play came from the UK, then they can take the whole $64k. AG and CR may agree that one play voids all winnings but a real court isn’t going to do that.
