That is not true. Gachapon mechanics existed long before, valve only took it to western market, not knowing the consequences. Remember this is way before gambling sites. It was a way to earn a cool random hat on TF2.
I'm aware of what Korean MMOs were doing years earlier, but it feels different, in a way I can't quite put into words. I suspect there's a psychological aspect to earning the chest and buying the key.
But yeah, maybe I'm pushing a distinction that doesn't exist, and it's all just forms of trading cards (which themselves were popularized by tobacco companies).
