Crypto gambling sites usually ask for KYC if they find something suspicious or shady related to the account in question. This is usually specified in their TOS and your situation does seem shady in my opinion.
If you refuse to provide your KYC to them, your problem won't get resolved which is why the decision lies in your hands.
