The straight definition for a professional is to "profess" if he does anything else than talking he is not a professional. If people reach him for a particular product, then he is not professing, he is creating, manufacturing, etc. Of course professionalism is associated to some traits, that you might have even if you are not a professional. Like responsibility for example.
Now if we go for the meme definition of professional (earning money for your job) he isnt a professional anyways, since it needs 50% of your monthly income to come from photographs to be called semipro and at least 75% to be a pro.
And trust me, this guys works at a factory or some shitty job, scamming retards like OP is a hobby.
