If you deposit the payment into an account that's not yours, that is where AML (and tax laws!) kick in. Are you simply giving a gift to that person? Are you buying something from them? Are you making a honest mistake? The problem is not that a casino "makes a lot of money" suddenly. Sure, great for them. But then if that money starts to percolate into the other jurisdictions. For example the casino orders dry cleaning from a foreign company. The casino wire transfers the money, the cleaners send the receipts, but no actual cleaning happens (obviously). And this is where banks come in, because they provide the wire transfer. And they are mandated to flag extremely successful dry cleaners and other providers, report it to various government agencies. And ... it turns out that somehow they can't even do plausible deniability properly.
