What is gambling? Does it need to involve money? What is money? Money is a human invention.

So is gambling about resources, power and status? If so then can gambling CS skins count? What about candy crush lootboxes?

If gambling is about risk, does parkour and base jumping count?

One of the most insidious forms of "gambling" I've seen is probably PvP matchmaking. I am fairly certain that games from Supercell have rigged their matchmaking to engineer a degree of frustration to keep you hooked. When you tie that to a ranking ladder it can get quite easy to get hooked
