Many people in this forum don't buy into the idea of AML assessments and classifying bitcoin in different groups based on their "dirtiness." Each bitcoin is the same as any other bitcoin on protocol-level. Anything else is just nonsense created by malicious institutions and their government buddies meant to control you, legally steal from you, and hold back bitcoin adoption as much as possible.

If you believe the "dirty" bitcoin hysteria, purchase your coins from a CEX and be willing to accept their terms and rules. Sell your coins back to this exchange when you are done. Avoid mixers, privacy tools, and online gambling if you decide to go this route.

If you don't care about it, purchase any bitcoin P2P or from no-KYC exchanges. You can find several such services on KYCnot.me. Use bitcoin the way you want to, without a malicious third-party setting the rules, and sell/swap them again P2P or via no-KYC exchanges.
