However, this won't mean that gambling is bad because it still depends on the gambler's behavior. In fact, there is a warning given to all gamblers "Gamble responsibly" but what really happens is that more gamblers become irresponsible. This happens because they can't control themselves and instead of making gambling as a sort of entertainment, they now consider it as other sources of income.
Nope, gambling is not bad, but rather gambling is addictive; gambling has the ability to take more than it can offer a gambler; gambling is for entertainment and not a primary means to archive wealth; winning in gambling is not guaranteed; and lastly, casinos care about their profit and not the losses of gamblers. If every gambler follows these ideas, they will not lose a lot of money to the casino, not knowing they are enriching the casino. If a casino has 5,000 gamblers losing $10 every day, you can imagine how much they are accumulating in 30 days; meanwhile, it is always a higher amount that is lost by the gambler.
