Indeed and that experienced gives you the confidence to keep playing for more, though it's a case to case situations where some might get addicted and some might gain knowledge it's on the gambler itself if you they'll take that experience and use it for their advantage, but for those who turned things into addiction most of them will either call it a scam or will surely regret participating on any types of gambling activities that they've involved with.
Those who make terrible financial mistakes and put the blame on gambling or call it a scam process are likely to do thesame to other opportunities that seem like using money to get extra money eg cryptocurrency, trading currency pairs. Because you gambling without getting addicted is a function of discipline. It's a state of mind that you alone can build for self, so if you don't learn to control your emotions you end up messing other things up because of your mindset.
Those who lose their money and say that gambling is a scam should check on themselves. No one suggest them to spend all of their money and lose it all in gambling but they choose doing that by themselves. So when they still saying that gambling is a scam, we can let them like that because we can not explain anything to them as they already close their minds from other people suggesting. They can get addicted to gambling anytime if they still difficult to control themselves especially if they keep playing gambling while they are saying that gambling is a scam.
