Yes, pretty much. But even machinists age and some of them move into managed facilities and then they have to leave their gear behind. It is super sad when it happens. And of course they really die as well...

I know a fairly large number of hobby machinists and some of them are quite advanced in age. They still turn out quality work, doing stuff that they love. But you can tell that in some of these cases the writing is on the wall and they'll stretch it as long as they can.
