Addiction comes when you lose a little amount of money every day and winning a huge amount of money after a couple loss. that's where it starts it's based on our emotion. When we think that we're making a lot of money through gambling we think that we're actually always winning without thinking that we already lost a lot of money upon playing it everyday. in terms of playing recklessly it mostly comes after a you win some and you constantly losing that's where it starts because you wanna feel that excitement again that feeling of winning. So you tend to bet higher in order to get your loses.
If you think that you will make a lot of money on gambling, then you clearly have a very poor understanding of how casinos work and your chances of winning. No, I'm not saying you can't win. You can win a huge amount of money that can completely change your life, but the probability of that happening is very low. I would advise you to study gambling a little deeper and maybe then you will reconsider your views on this entertainment and will visit the casino not to win a large sum of money and for the emotions of the game of chance and expectation.
