No, it's just wordplay.

Capital is always at risk in financial investments.

If there is a semantic difference, I'd say you "invest" when you have a historical expectation of future positive returns, and you "bet" when you're taking a contrarian approach or just going with a gut feeling when data isn't available or known.

Anecdotally, and personally, I've had better luck with "bets" than "investments". But they're fundamentally the same thing.
