Gambling is not a scam and it's often quoted as one of the oldest pastimes in history. There are no doubt scams that can be run, if but it requires learning how each game works and how it might be abused. Take roulette for example, it gives a tiny advantage to the house that will take your money if you play it long enough - but you might get ahead for short periods. That being said, like every part of life, there will be fraudsters who create completely fake gambling sites with the intention to steal money and can be very sophisticated in their methods. Using general common sense and applying life experience is the only way to avoid being taken.
Scam in gambling can be said to be a casino thing, that is to say that some casino could decide to become scams, just like 1xbit and it sister companies, but at that we can call their actions scams but to generalized things and call gambling as an entire scam activities is somewhat out of context and should be looked into properly before making such a statement, we have hard alot of misconceptions in the past, and to be honest, gambling will continue to have such stereotype as scam in itself, and this is pour false claims.
Also why many people thinks that gambling is scam is because of the outcomes and their experience, some people may have bet on a game, and the thinks and believe their going to win, but when the casinos apply the in House rules on them, they will realize that the list the game eventually which makes them assume that the casinos scam them all time, or saying that gambling is entirely scam.
Such forks that make such statements do that out of the fact that they lack the basic understanding of what gambling is all about, and how to control themselves around gambling or while gambling because some risk much more than they could, and when they lose they tend to become so provoked to makes those concluding statements that gambling is a scam.
