The thrill and excitement in gambling comes from the money involved in casinos, not the games itself. Its the same games repeated over and over again in different formats only but the money is what drives them.
People dont actually enjoy losing but they want that win that might come after the loss because they are banking on it. Also the physical casinos are built in a manner to make the player lose track of time.
However this hope often leads them to a circle or loss and despair.
Certainly, money is a natural trigger to alot of activities.It holds a big connection to deriving excitement and the expressive moments/experience that's involved.Asides even gambling,a lot of individuals are practically wired by the mention of "money."The only reason certain people are involved in various activities is actually because of the availability for money.
No doubt, money is the primary factor that motivates people to want to gamble at all times, and ad such, it is obvious, nobody wants to lose the little they have got to gambling, but will be happy to double or triple their money when they are lucky to hit a jackpot. And In regards to what O.P said, it is only possible for people to enjoy gambling when they lose an amount they were ready and willing to lose while gambling.
