I believe more in luck when it comes to gambling. If I gamble and it's my lucky day, I'll win. If I don't win, I have to accept it because that's the best way to go.
But on the other hand, I have friends who also enjoy gambling, and we always share our winnings when one of us wins.
You don’t really need partners if you believe winning is all just luck. But the reason why some gamblers or bettors team up with others is so they can share strategies. From there, they can build something better together hoping it helps them improve and actually become profitable in the long run.
