Yes. Or else it wasn't so sudden, but you just noticed. Can't be proved either way. Doesn't matter.

So then it is common for sebaceous prominence to show up suddenly as you get older?
Yes, I think so. Besides being in the same vicinity, they have nothing to do with each other. It's possible that you had them for a while but never looked too hard (why would you?) until a wart drew your attention to these spots. In any case, show them to a doctor next time you go, but I doubt you have anything to be concerned about.
Take care.
