You are not wrong actually, because lot of gamblers that are not disciplined are failing to make the right decisions on their gambling behavior, not winning in gamble is normal because it's not every time or every season that a gambler must win. Winning can be in just a few seconds and losing might be 345 days a year, but the important things a gambler should do is to use the money he won from bets responsibly. I suggest that any gambler who is gambling for money should be able to use his winnings responsible, no matter how small or how big it is. Achieving any thing in gamble is not a bad idea because money are ment to be used.
I agree to the fact that not winning is a normal occurrence because you can't be right with your predictions all the time and if you do and others aswell does then in no time the casinos Will be shutting down because if everyone or right nd winning then they are definitely not going to be making profit off the casinos anymore so they may go bankrupt paying winners and ending up closing down the casinos. Responsible gambling still applies even after winning a game, it's expected you be smart enough with how well you get to utilize your profits made off gambling but sadly some gamblers aren't Smart up till that point as they get to lavish their winnings some times.
If you get to make sure to achieve something very tangible from your profit off gambling, it's very likely that in the nearest future you will be proud you ever did and you will still have something to fall back at so as to be able to still gamble again of the need be.
