They often have a card to use in their TOS, maybe stating they have right to change their TOS at anytime or some might state when they can request KYC from customer, which some may even say at anytime but if the customer do not go through it carefully, they won't see this and miss out thinking the casino is fully non-kyc.
Which is illegal anyhow, Casinos could write whatever they want in the ToS that doesn't mean a thing in court.
They could for example, add that in case of multiple winnings, they will only pay in cash at their home office, so if you win over 10k, you need to fly to Curacao, would that be legal just because they wrote it in their ToS?
It's not a scam but of course It can be questioned....
Most of casinos have in place a forced KYC in any case for all players involved.

If a casino can accept money from a stranger without KYC, then they can also pay that stranger the winnings without KYC. It is selective scamming, fishing for people who will not be able to provide such documents or who, for various reasons, have problems with their papers. For example, I had no utility bill in my name for a while, since while we were finishing the new house we stayed at my wife's previous apartment for three months. If they had demanded such a document during that time, I would have had nothing to offer.
