Risk taking is not gambling. Taking a risk involves an unknown (maybe unlimited) upside. Gambling has its ceiling. You could lose it all, but you can only win so much.
When Mark Zuckerberg invented Facebook, nobody predicted it would grow as massive as it did. Same with Google, Apple, the invention of the internet, the car, and electricity.
Up front risk, reputation and money on the line, but an upside so great it was never predicted by the wise men of the time.
Risk taking is not gambling, it’s much more useful and way more fun.
