One of the biggest advantages of KYC is in terms of the security of our assets, but we also cannot rule out our data security. I think KYC is still in gray thinking, so I can't give more opinions about this.
And I think the OP is feeling annoyed because it can't play gambling because it's limited by KYC. I think this kind of policy on the platform that publishes KYC must be removed and replaced by doing KYC when you want to withdraw funds or be given a limit on withdrawing funds to do KYC.
