I'd agree with the blackjack comparison, but not roulette. Both "futures betting" and blackjack need skill to be able to win even if luck plays a significant part, as opposed to roulette, which is just pure luck.

Roulette is not pure luck, the amount of skill needed is just significantly higher.

Well the real insight here is that most "investing" is gambling.
