I would say gambling ain't scam because you get results sometimes it might be delayed or hasten. Gambling with your hard earned money worth it tho especially when you are getting what you want, and it's based on the fact that we all have different reasons why we go into gambling, I might be gambling for money and you are gambling for fun but getting it just as you want makes it worth but that not withstanding it's so cool to gamble with what you can afford to lose and be rest assured you ain't scammed of your money especially for those wanting to get more y out of it.
For some reason, when a player wins, he is happy with everything, but when he loses big money, gambling immediately turns into a scam. In gambling, everything that concerns money before the bet is controlled by the player, which means that all his actions depend only on him, everything that happens next is a game and if he started it, then he agrees with the rules and how it all happens. Therefore, there is no point in talking about whether it is a scam or not, if you agree with the casino rules.
