If a person is very knowledgeable to math, I know for sure that he knows the risk of betting and gambling because he knew how probability works. Only few people who will believe the gambling is a scam, and those people that loses everyday and doesn’t have plans or allocations in money. People that blind betting and keep losing will make them think that gambling is a scam. Especially if a platform have an algorithm of making all the odds in favor of the house.
That’s why you really need to study and research before spending too much money and just losing. It’s okay to be knowledgeable and know the risk of things you’re interacting with.
Maths or no math, the name alone is what explains it all, it's a game of chance and a game based on luck, anyone that doesn't know all those things should blame their self for being so ignorant to ignore the knowledge of what they are involved into. Anyone that starts gambling and realize that it's not what they expected, let the person quite or prepare to lose more.
