I think you are drawing a distinction between games where the odds are constant and built into the game, (eg roulette), and games where there is a degree of skill involved but still an element of chance, eg. sports betting where a person with extraordinary insight or privileged information will win more often in the long run than a person who just bets on their favorite team every Sunday.
Arguably stock trading and poker fall into this same category.<p>For some people though this is just plain betting. They don&#x27;t have a strategy or an angle, they just believe they might get lucky and for these people this form of behavior equates games with skill to rote gambling.
