I think you would definitely qualify! The portfolio thing is mainly, I expect, to both have a place to send people who see the artworks and want to know more about that artist, as well as letting him look at other works so he can see that it is genuinely made by you.
I don't think it's really needed but it generally wouldn't hurt to have someplace online you can send people who are interested in your art.
I have my old blog, my old etsy and the tumblr account that went with it, Facebook and instagram. None are really active now since I'm pulling back on using those platforms, but they do show a long history of work. I've started putting up newer stuff on bluesky but haven't posted much yet.
You could even just link to your art stuff here.
With our move, and setting up the new house, along with dealing with some family stuff, I just haven't done much making of art in the past three years or so. I'll have to figure out where the new stuff will go soon!
