Even though well taken care of, I realize the boat is 25 yr old. but
with the care I take of it plus the previous owners, can a floor just
normally rot out when it's kept normally dry?

I hate pulling the seats, peeling off the carpet and replacing the
wood.

The problem is the carpet. It retains moisture and creates a warm
dark place next to the wood, just what rot likes best. My old
runabout was a 1979 Winner 24 which was a pretty well built boat but
it eventually developed floor rot in one area that was carpeted.
