I think a lot of people are aware of this but most of them decided to keep on playing. Even in real casinos theres still cheat and the only real winner are those casinos. Gambling is risky but its quiet more risk if you do it online cause its the syatem that works for it.
That is not a scam per se. Actually every gamble is a risk and people are aware of the risk before they set their bet. That is again unbiased by the provably fair system. Any player who loses money by betting cannot call the casino a scam because they risked their money and thus they are responsible for their loss and not the casino. Moreover you cannot sue the casino because they have ToS which is blindly accepted by the player before playing any game that will always save them from litigation.
