How is that obvious? I'm not sure how those are connected. Maybe for a specific game, if that game has lootbox-like mechanics?
In this sense, gambling is just about rising the stakes to get that emotional hit when just fake points don't do it for you anymore.
I'm assuming that most online gambling is like poker where there is a degree, or at least an illusion, of skill and agency. Having some randomness involved is also quite appealing because you can keep hoping to get lucky and can win now and then even if you are not great at the game, it can still be fun to win even if you didn't really earn it. But I doubt many teenagers just keep pressing a button like in roulette or slots.
Well there is loot-boxes of course, but that's more engaging since the rewards are tied to an actual game, there's the chance to show-off your winnings in the case of cosmetics, the collectable nature of the rewards, and sometimes the possibility to trade them for other items or real money.
EDIT: There's also sports gambling which is massive, although not sure if there is any overlap with these people that flow from gaming.
There are lots of similar tools that casino owners/game designers/sports betting apps/social media/&c use to build addiction into their products, all while offloading responsibility onto individual consumers.
A really interesting study of this is the book 'Addiction by Design' by Natasha Dow Schüll examines this in the context of slot machines/video poker/casino games, but you can see the same process at work basically wherever you look.
Their data is lacking to draw strong conclusions, but the question is interesting.
I know more than a few degenerate gamblers. My one buddy bets ~250k/yr, the rest are about ~100k. I'm like 10k (and through luck or skill I end every year up between 2-10k).
I'm the only gamer of this group of 10 people, even as kids.
Poof on the other hand, could be taken as a slur, sure.
Let’s relax.
In PUBG: You walk into a house not knowing whats there. You find 'loot', you hoard it...and then maybe you get into a fight somewhere along the way. The game is 70% looting, 20% running and sometimes as little as 10% fighting other players. The looting is designed to feel like gambling.
And i freaking love it.
That's all to say, there's certainly rules and structure to the game, but a lot of what hooks me to these styles of games is the chance element. I just didn't realize until very recently (I'm now 39...took a minute to pickup on it)
Types of gambling could be sorted by how much control you have over the probabilities.
(The cosmetic gambling obviously is very much gambling, though, and is unfortunatly a big part of the game.)
That doesn't mean that gaming makes you like gambling. There are many player archetypes, some of which get enjoyment out of games from factors that are quite dissimilar from gambling, and they will probably never gravitate towards it. I could see the reverse being true though, probably gambling does make you like some kinds of gaming.
Also, this is saying that online gaming is correlated with online gambling. Well yeah, it's all sitting at the computer playing competitive games against strangers, money or not it's a similar activity.
Indeed, they show no correlation between "playing games at 9" and "online gambling at 20". It might be the age difference, but it also might be that gaming in general has little correlation with online gambling, it's just competitive online gaming that correlates, which makes a lot of sense.
