Thinking the company needs you to lose every bet.
Gambling businesses can pay out winners and still make money overall.
A casino game with a house edge is priced to favor the operator over a large volume of play. Individual players can win, sometimes a lot, without disproving that advantage.
A sportsbook’s prices generally include a margin too, although its results also depend on which bets customers place and what happens in the events. It can lose money on a particular game.
Other gambling businesses charge a fee, such as a poker room taking a cut from play. The details differ, but someone winning is compatible with the business earning money.
“The house always wins” is too simple. Understanding how the company is paid tells you more than assuming every individual wager must lose.
