Could be in any context. I do it a little on UFC fights but that’s a relatively low amount and I can afford I to lose any time I do. It seems like it’s becoming a really wide spread problem though, at least in the US. At the same time I don’t see why it should be illegal. Granted I also don’t think any drug should be illegal.
I don’t really understand it. What’s the appeal? Personally, at least, the moment I realise that there’s nothing I can do in a game that affects whether I win or lose, I lose interest in it completely. Well, it’s not like I’m completely oblivious to the mechanisms here, I also get a little dopamine boost when, for example, I get a critical hit in a video game and disappointed when an attack misses, even though I can only vaguely influence the probabilities of those things happening, but that only works as a little constant pleasure differential as seasoning to keep you on your toes, it would be completely pointless as something that cumulates into a single climax.
The closest I’ve come to understanding the appeal is that the thrill of not just possibly winning money but also the risk of losing the fruits of your labour (i.e. “real stakes”, even if small), is pleasurable to some people…? But if that’s what it is, quite frankly, that’s seems less like seeking simple pleasure and more in the realm of depravity.
Anyway, I do think gambling is one of the dumbest dumbass dumb-dumb thing a person can do that doesn’t involve scooping out your eyeballs with a dirty plastic spork. Even putting aside that the odds are never in your favour and so, it isn’t rational thing to do, someone who starts gambling may not know they have the kind of addictive personality that gets them sinking into a bog, because that part of their character may have never surfaced, or only in low-stakes situations. So they’re not just gambling with money, they’re gambling with the very quality of their life.
Also, betting is just an inherently corrupting force. Even if you’re only making small bets, even if you’re not pressuring competitors to throw the match (if you even have the means to do so) or throwing banana peels into the ring to get the person you bet against to slip and fall or something, you’re contributing to the payout to the people who are, incentivising that behaviour. There’s no high payout for betting against the odds (and then working to make the unlikely the inevitable) if there’s not enough livestock contributing to the pot.
