Tl;dr, but I get what you're trying to say, everyone who owns Photoshop calls themselves a GFX Professional and I agree, it gets really annoying.
I'm a GFX artist myself, and IMO, I do good GFX but I wouldn't call myself an expert or a professional on it. I've been doing GFX for about 5-6 years now, on and off, and I can at least say that I have a sense of flow in what I do.
