The only wrong misconception on this topic is people keep assuming that game can be use as way to earn profit long term while it’s purpose is to provide entertainment.
The expectation vs reality create many misconceptions that makes people think that gambling only gives loss while fun and entertainment is its main product.
As the title says, let’s be specific when it comes to slots in casinos, I really think they’re designed for us to lose since the house edge is very high. Yet despite that, slots are still one of the most popular games.
But not all casino games are like that. Some actually allow us to use skills, for example, poker. We go to casinos to play it, and if you’ve got the skills, there’s a real chance to win. So I think it’s wrong to just generalize that “casinos are designed to make us lose” without mentioning the specific game. It’s not the same across all of them.
