They are not looking at it as their fault but instead convincing themselve that it's someone who should be blame, pointing thier fingers as they don't want to stop and just wanted to continue playing, something that addiction can do, it's blinded your mind to please the lust and pleasure that you are aiming to achieved when you are in game or in sesssions.
If you can't control yourself then better not step foot into this venue, you'll regret it once you realize your mistake.
I consider a scam to be everything where there are scammers who are aimed at robbing their victim. And when you decide to play gambling, there must be responsibility and an understanding that there are big risks, there are losses that you need to be prepared for. Gambling is not an easy task, I think that when they say that most players lose more than they win, this is true, but this does not mean that it is a scam.
