We make the problems itself and due to that I do not think gambling is wrong.
That's the thing said rightly but you said it in a confusing manner.
We are actually doing it wrong, not by getting addicted to it but taking wrong decisions and when we know that we are taking wrong decisions, we should stop gambling for some time and come back later. That's the way to do it right as we will lose less this way.
Yup....The house games are intended for entertainment only, like movies or carnival rides. When you pay for a ticket to see a movie or buy a ticket for a carnival ride, you don't expect a monetary return on your investment because you are doing it for fun, to be entertained. If a person goes into a casino expecting a return on negative expected value games, then they are missing the point. It's not wrong to be entertained....its wrong to expect a return when you know you're playing against the odds.
