I used to play full-time and I currently work in trading.

Poker is definitely gambling. Casinos are gambling, they’re just doing so with massive volume and tiny risk (afaik). Trading is gambling. Gambling well is a subset of gambling.

I think I would be OK if we wanted to define all endeavors with an unsure outcome gambling, but I believe that makes most things in life gambling which means we need another word for especially risky endeavors with an unsure outcome.

I think we have the same concept, but I'd be happy to call trading gambling if playing poker table games was called gambooooling.

I think if we have to make a distinction, then categorizing games of chance where you're wagering money or direct money equivalent seems like a fair one. And in that sense, I wouldn't consider every trip I make to a hole in the wall eatery gambling.
