I sort of mixed up risk and gamble in that analogy. I stand by the part that many games fall on a spectrum between “game” and “gamble”. counter strike, wow, eve online are games with a gambling element: loot boxes, skins, etc. Poker is a gamble with a game element, e.g, bluffing. Slot machines aren’t games at all.

I think cryptokitties is somewhere between Poker and Slot machines.
