I've spent lots of money on skins in CSGO League of legends Fortnite...
if i saved that money i could've bought a nice car by now
Dude are you serious?
I don't spend that much in games even if I like it. And if I spend a lot, it won't be the same as you that you can buy your car, that's just too much.
There are people who spend $10K in a day for a lucky spin on that day so yes those kind of people are also existing and to be honest not everyone can afford it still they are doing because they are addicted to it and they may be looking for sponsors or even spend from own pocket but at the same time they don't know what they are going to do for the next day meal.
