Other than the possibility of a chance to win a life-changing sum, the only thing I can see a positive side to is the games that take place in groups. I mean here in particular the communities of competitive gambling, where the game is always in the form of groups. Competitive gaming communities create a sense of belonging, where people who share the same passion for the game come together and encourage each other. Competitive win games offer a fun and competitive experience, encouraging enjoyment and excitement.
For example poker. Poker is a popular social game, where players gather around a table and interact with each other through betting and discussions about playing strategies. Players of different levels can learn from each other by sharing tips and strategies. Poker can be a fun and entertaining game, especially when played with friends.
