I have used more or less most of the popular cases on this forum. And almost most casinos allow small gamblers to withdraw small amounts without kyc. Like I use stake regularly without any KYC and withdraw some btc from there every week. sportsbet.io also offers kyc free withdrawal and coinplay also offers kyc free withdrawal for small amounts as per my knowledge. So you can definitely use casino sites without kyc if you are a small gambler. It will not be a big problem
Its that you will enjoy KYC free experience on casino if you are small player but theres limit on this when you reach the minimum amount allowed for the total balance you deposit in the casino. This is not a danger for those small players that is not frequently playing but you might be required to do KYC in the future if you are always depositing money with just small amount.
