A pro can really make money from gambling but they are also getting lost like others but well, they have more control than the others so they can come back to the gambling the next day and recover their losses.
Actually, you can use your free time to do other things instead of playing gambling because that will be worth it for you to prevent the loss from gambling.
But once we know to gamble, the curiosity will come to us even we break for some days.
How many pros are out there that can really make a living from gambling? I do believe there are players that can make a profit out of sportsbetting (if you really follow certain sports), but from playing casino games it is different as it is 99% based on luck. I have yet to find a strategy that always wins lol.
