If I'll be asked about this, I don't think I can do this immediately because there is no street sign on the place where I live but I need to travel in the town first lol. Usually, KYC is asked if the withdrawal amount is huge. I think that is for them to know that it wasn't a laundered money and also to know that the original owner still controls the account. There are still gambling sites who can ask a KYC at the start or even if the withdrawn money is only small.
Can't say that it's for huge amount on each casino as some has strict policies for base levels also but if you are fine with uploading selfie with a street sign you are comfortable to withdraw huge amounts also without any worries but for me small gambling with minimal KYC is fine.
