My parrot vomited today...help

My 10 month old Green cheek conure vomited earlier today. (Definitely not regurgitation, he was flinging vomit around...) I've changed nothing in his cage/diet. I honestly have no idea what could have caused it.

It's been about 8 hours since he vomited, he's drank water, ate food, he's active and his poop looks nice and solid. But everywhere I look online tells me their bird died hours after vomiting and it's making me panic. I tried to give him time to see if he'd get better, which I think he has, but at what point does vomiting become a real concern?

I appreciate any advice. Thank you!
