A lot of us say that if we want to win, we need luck. But is that really how it works?
I mean, luck isn’t something we can control or predict, it just comes when it wants, and sometimes, not at all.
"We need luck" is different from "we want luck." These two are what gamblers mistake for each other, and now again, you are mistaken it in people's expressions.
In casino games, we can't win against algorithms, so we surely "need luck" to win. The same thing goes for sports betting, though, skills/expertise are needed in this category, but still, "luck is needed" too However, if you are now carelessly "wanting the luck," that's the stupid aspect, and this is what you are mistaking for the expression of most people regarding luck.
