I don't know about crypto based casino's though, I mean we only have usernames and such so even if they put it in public no one will know the real names behind it.
And the last one that I heard that won a raffle here in our community with a Cyber Tesla Truck is SyGambler.
Depends on the state because I reckon there are still some states in the US that will give you some option whether you wanted to be publicized or not, but in most cases and states, you don't have that much option because I've read that they have a law about that already that a lottery winner can't be remain anonymous.
It is a huge disadvantage of course because you aren't that much safe anymore compared to the day that nobody bothered to know you. But in online casinos, the situation might be different though, except in the offline casinos where you need to go to the place and play.
