It's a thing you can expect to happen, like falling while downhill skiing. Only the most extreme situations are like "if you fall, you die". If it's like that every time you go out, the prognosis is grim.
EDIT: I can actually count on one hand the number of times I've been in situations like that and while it's a hell of a lot of fun it's not something you bring your friends, family, children, etc along for..
I’ve only been sailing a few years, but I racked up about 500nm of racing this summer. I’ve only been in these situations a few times, but had a ton of confidence in the boat and the skipper. It’s honestly a ton of fun, and feels more dangerous than it is, since the boats are (supposed to be) designed to handle this. That said, I keep the family away from this sort of thing, and take them out on our family friendly coastal cruiser for more leisurely sails.
In order to enter e.g. the Newport-Bermuda race you need a minimum stability rating of 115. IIRC Bayesian's angle of vanishing stability was 75° keel up, and the vents started taking on dangerous amounts of water at 45°. That's not a boat I'd ever feel safe on! The skiing analogy would be like every single run is maximum consequence.
