Most of the casinos do look at what country you are from and base their regulations on their judgment as to whether they will require you to undergo KYC or not. I have friends who are into sports betting or gambling in casinos, but they are not required to go through KYC, just like me. Therefore, we enjoy the full liberty of gambling anonymously.
We feel lucky if we can get a casino that doesn't ask us to do KYC because that means we get complete freedom in gambling. But if we don't pay attention or control ourselves, that's when we can start experiencing gambling addiction without realizing it. The casino will check which country we are from and will apply the same rules as other members. But if the casino asks us to do KYC one day, we have to be careful and check the casino to ensure that the casino is trusted.
