Linguists would tell you that Scots is a sibling to English rather than just a dialect of English, having both descended from Middle English and that the dialect of English people in Scotland speak is instead "Scottish English". In practice of course humans don't language tag their speech (indeed they rarely even language tag written text) so it's murky. Maybe one word in ten that a Scottish bloke just said to confuse a tourist was technically Scots not Scottish English and perhaps some of it was even Gaelic. The important thing was that they confused the tourist as desired, for which frankly even an inside joke would work.
Sociolects are fun. In one of my friend circles the word "fish" is understood to mean the controller for a video game, I don't know why exactly, but if you said to one of us "Pass the fish" they'd hand you a controller without even seeming puzzled, that's just obviously what you'd call it. But in another circle it means nothing and you'd be greeted with confusion.
This means that AAV is culturally important, but there's not necessarily the same sense of "this is a separate language" that there is with Scots, even though in many ways it has all the same claims of being one.
It would be exceedingly difficult to strongly distinguish it from "Gen Whatever Slang" or "US Slang" or a lot of "LGTBQ Slang" etc etc. The list goes on.
