Bluffing in poker is not cheating, is it? This guy bluffed that he want to sell when he did not.

I believe if you cheat at a casino, you are just banned and kicked out.

Also, perhaps there is a differentiation between working within the mechanics of a system to cheat, and going around a system to cheat. An example from the esports league would be the difference between using a corner case to shoot through a wall, versus hacking into the server and modifying the code.

If you don't cheat, but do something the casino doesn't approve of you are kicked out. If you actually cheat, and the casino decides it is worth it, you'll have the government come down on you too.
