Can’t be right, can it? It would make the Sun (over 4 billion years old) an enormous outlier.

It also would mean stars, on average, do not get very old. Over 10% of the stars that the ancient Greeks saw in the sky would have to have gone supernova since then.

Yes. That fact that I'm thinking made me think I was certainly wrong

Not all stars can go supernova. Sol will never go supernova. Only very massive stars can—or stars that become very massive by absorbing other stars.

Binary white dwarf systems can also go supernova, even if the combined mass is not that large as far as stars go.
