I’ve got quite a bit of experience with Linux and I manage a home server, but that probably doesn’t differentiate me much. I’m honestly interested in most things computer related, but don’t know of any specific fields to seek out.

But yes, there is a chance in it. This experience can give you a head start into cloud computing technologies, virtualisation, virtual networking, kubernetes etc. For a good many current IT experts this is still a hornet’s nest where they don’t even dare to stick their nose in, and a lot of others can use it, but never become experts there.
