The day a gambler starts owning up to responsibilities then he's mentally mature. A lot of gamblers lose money and out of anger they start blaming the casino for their losses. It's a different case when your wins are withheld or not properly settled but in a case whereby you placed a bet and lost there's no point in trying to blame the casino for your own actions. It's a game and whether you like it or not you signed up to win or lose when you staked
You're right.
A lot of gamblers forget that the odds are always in favour of the house and not the other way around. Meaning that, the gamblers are expected to lose more often than they win and thats the reality of gambling, but it's quite unfortunate that so many gamblers are ignorant of this fact and then they end up taking careless risks and having expectations that are just so unrealistic. The more gamblers learn their place in gambling, the more likely they are to make better gambling decisions and avoid more losses.
