You just got to explore a little bit. So like "pcgaming" and "pcgamer" are tags that exist. Also a tag always exists, it just might not be popular or have been posted on yet in awhile or yet at all.

I check alphabetical the full list of tags and you can't find "pc" or "pcgaming" should be between "painting" and "people" but isn't...

You should be able to just navigate to the tag and see what's there and go off that

There are a few tags that don't exist - fun things happen when you try to make your first tag "new" for instance - but yes, for most the problem is in Steemit's listing, not in the tags themselves.

You're very right. We've seen busy for example use more tags
