For "I bet", the stress matters too. "I BET you did" can be suspicious, not just a normal guess.

I hear "safe bet" much more than real gambling bet in office chat. like "thai food is a safe bet" = nobody will complain

In business/news writing, "bet on" often means backing a plan with money or reputation, not literally gambling. A company can bet big on electric cars, or investors can bet against a stock. Learners sometimes translate it too literally.

Bare "bet" can also mean challenge accepted. Like "you wont finish that by Friday" - "bet". Not yes exactly, more like ok watch me

Small learner trap: "you bet" is not just a longer version of the new slang "bet". In the US, "you bet" can answer thank you, like "no problem". If someone says "thanks for the ride" and you answer only "bet", that sounds way more young/slangy, maybe weird from a non native speaker.
