I had COVID in May, and have influenza B now. I’d rather covid again in short term, as short term flu symptoms are worse. However, I also feel like I never really got over COvid and long COvid effects are a thing.

It's not really luck. The chances of hospitalization were always low even with middle aged people, but if you are triple vaccinated your odds of hospitalization are EXCEPTIONALLY low. As such it's misleading to call me "lucky" for not suffering a bad outcome.

A segment of the population is always going to die from diseases that are broadly innocuous, that's just the human condition, but that doesn't mean the diseases are broadly dangerous to a vaccinated population.
