That's exactly what happens. The KYC policy for big wins at all casinos that accept payments in cryptocurrency is pretty much the same anyway. And all gamblers now know this very well and almost all gamblers are internally prepared for two possible outcomes in case of winning. Either the player gives the casino their exact personal data and will receive the money they won. Or the player cannot lose their anonymity under any circumstances and cannot or does not want to give their personal data and then will naturally lose all the money they won. In my opinion, this vision of the situation is now generally accepted and does not present any other solution to the issue to anyone. For example, how to receive a bunch of money won and remain anonymous, which could easily have been done ten years ago.
