So yatzee is gambling arv never spent any money doing these loot crates. You are spending points to get something in return gambling means you could get nothing in return. Buying groceries isn't gambling yes you are losing money but you are getting things in return. Not liking what you get in return isn't gambling it just means you didn't like what your got winning a prize every time does not equal gambling
If you buy a chance product, hoping to get a certain good item, then it's gambling. If you get worthless crap then you might as well "win" nothing. Some lottery tickets cost $20. People can then win $5, a coupon, or even nothing. Those people consider themselves losers even if they "won". To make up for losing they buy more lottery tickets, wasting money, then they can get addicted. That's why gambling is regulated in most places. Lootboxes is gambling. If it should be regulated under gambling laws is another discussion.
You are essentially trying to collect them all only the pickiest person would go for one thing ---
