The money earned by hard work doesn't mean all people have money management skills and all people know where to invest their earned money and where is not. If it is the words of scam then everyone must have to stay away from being scammed I do not think gambling is scamming so I do not think we should stay away from gambling but we do not invest all of our funds as we may not be afford that if we lose on that gambling.
True, gambling is a very clear proposition, there are odds for the gambler to win or lose, and the odds are against the gambler.
It is the gambler who decides to go and bet with those unfavorable odds.
It's not a scam if you simply communicate a bad deal and the other person agrees to do it.
It would be a scam for example if the casino actually don't pay your money, or something like that.
