The idea behind gambling is rooted in our desire for risk, reward , and entertainment. Some people engage in gambling not just for making money but also for the thrill of taking chances and social interactions. As gambling it’s not just limited to staking bets as we call it. Some gamble by playing poker, whot and Luda etc because it provides opportunity for socializing and competitions. While others are motivated to gamble for just the financial gain
I doubt socializing and competing are main motive anymore for gambling esports that online casino are already popular now. It’s more own lquick gain” objective rather than socializing because most gambler nowadays doesn’t frequently use chats to interact when login in the casino.
You can by beer to have fun and not seeing it as a waste of money. You can give a friend little amount of money in a way he may want to give you back but you will not collect it as you see it as small amount, telling him it is a small amount of money. Only such money like that, that are small in amount set aside should only be used for gambling. That is the meaning. The fun you see there does not necessary mean fun. Just like an ideom.
I like this interpretation of having fun. We sometimes spend our money to get fun/entertainment. Same as gambling, we are paying for the chance to win money through taking risk which gives the entertainment part. People that missing the whole point of entertainment are frequently those focus on gains alone and forgot to cherish the games when they are taking risk.
