Of course it's a scam. Go on and find me a casino that gives you better odds than the house? Go on and count how many casinos in this board are truly provably fair, and not just praying on idiots to try their games that are more than likely to be rigged (even more so than the odds being rigged against you, which is simply a fact when it comes to all forms of gambling where you play against the house).
No, it's not worth gambling with your hard earned money.
I think it depends on how you define a scam.
The casinos clearly indicate their odds. They operate under those odds, and the gamblers are aware of that.
I wouldn't call that a scam, as everyone involved knows the rules, and proceeds to engage, or not, in a transaction.
A scam in my view would be a casino operating with different odds than the ones published. Imagine a coin toss where the odds are not 50/50 but 70/30 for example, that would be a scam in my mind. But if it is 50/50 and say, they charge you a fee per coin toss, then that's not a scam in my mind even though they are going to end up winning more money than you in the long term.
