Everyone who understands how RTP works know that everyone time you wager an amount on a casino, the casinos keeps a small cut and pays you back 90-95% back, based on the house edge. That means if you keep gambling more and more you are just going to lose more money mathematically. But someone who is addicted is like a possessed person and it's impossible to explain them anything.
This is true about RTP, but what I noticed is that casino is far more than those in term of losses because as I am gambling, I noticed abruptly loss than what is stated as RTP. Also if someone is not having gambling experience, the person may not known when he will start to increase the money he is using to bet because he wants to earn back the money that has been lost, but this will result to more losses in most cases.
