It depends on your view about what scam is, because for me scam is a trickish way of deceiving people to extort money from them whether directly or indirectly. But in gambling the case is different because casino or gambling is made in a situation where people will try out their lucky if they can be able to win or not. Gambling is not a must it is a game of willingness for a person to decide, but not in any way a scam. It can only be a scam when you lose often than win. Meaning that someone who often lose will see gambling as scam but but not applicable to a person who wins regularly.
gambling is basically an activity that involves luck to get a profit, besides that when they will gamble it is their own will not a demand from the casino there is no element of coercion that the casino does to other people for them to gamble. Unfortunately, not a few people think that winning in gambling will be easy to get so they tend to ignore the risk of greater defeat.people who often experience defeat in my opinion they can not consider gambling a fraud because if their mindset by gambling is for entertainment then there will be no thought that gambling is a fraud, so in my opinion people who have the wrong response will say gambling is a fraud.
, so is the gambler who has great expectations of winning and even in the end the unrealistic mindset and expectations are often the root of the problem in gambling, the hope of winning big can make someone continue to gamble and even those who win big will also be difficult to stop in pursuit of greed which in the end gamblers are trapped in huge losses that destroy their lives.
