Does the type of game you play at a casino or sports you bet on show an individual's level of intelligence or how smart a person is?
Blackjack, Poker, slots, roulette, baccarat, sports betting, horse racing, betting on sociopolitical events, keno, etc.
Basically, not a thing to consider as a measurement of a person's level of intelligence on how they play gambling. However, you need to have that kind of intelligence about a certain gambling game. It's an advantage to consider especially those card games as you faced other players too that you don't know if some are those are really highly skilled. Being smart will always come from understanding how the game works.
Not just that, aside from we need intelligence about a gambling game, being smart on how to manage properly the bankroll is one of the key factors in order to lasts long in gambling. We should always think of an effective way how to maintain our winning stats over losing stats as in the first place there's no 100% guaranteed wins in whatever gambling types.
Also, consider those who are just basically having their own good times.
As you don't need to think hard on your games, you just play those luck-based games.
So the intelligence is indeed not a question here. You can't judge a person on this level.
And do remember, the tips, knowledge and strategies in other games like poker and sportsbetting are acquired throughout the years.
So it is not only about intelligence but patience is involved. And not many people have such patience of heading this direction.
