Considering the GDPR doesn’t really give you the right to sue by yourself and that the best you can hope is for the regulator to fight for your case, I’m not sure the profession of the data subject would matter.
Keep in mind that the regulator who’s supposed to regulate them is corrupt and complicit so it’s very unlikely anything would work.
I'd like to see an actual lawyer try it and document the effort with similar rigor. I wonder what the response from FB would be.
