Gambling is a game of chance. It is combination of skills and luck which is really a risk on your end if you will play and bet. To avoid such, you must set limitations for yourself. Time, effort, and time are usually the most common things sacrificed in gambling. If you aren't ready for the consequences then set boundaries or just don't play or bet at all.
Yup, gambling losses cannot be delegated to other people, no matter you do. Every gambler shoud be rememblers will not get anything, unless there is evidence that the dealer is committing fraud. As long as we gamble consciously when we lose, then at that time we should also be aware that this loses is our responsibility, not for blaming other people.
