Of course it is wrong! There is almost nothing benefieatial in gambling except from learning how
houses work, what a house edge is and how to calculate odds and house edge, and maybe some probability theory.
After that, you end up owning considerably less money!
Not all gambling games are against the house.
Poker, sportsbetting, event betting, etc. are against other people, and the house only takes a small comission there on the profits.
You can have real edge there. I heard that pro english horse-betters usually earn 50,000-100,000 pounds yearly just by knowing the horses throughoutly.
