Random kid more in the sense of no background affiliation, like Lee/tenten/Sakura
Opposed to Neji/kiba/shikamaru/sasuke and everyone else..
They all have family history backin up their growth, feeding jutsus.
Lee/TenTen/Sakura.. only got hard work and theirs own drive.
I'd hope naruto was one, but being 4th, is just a plot to make him better.
Of course naruto grown alone, but still genes are there.
Kinda like Neji came up with Hakke by himself, because he had the strongest genes/byakugan..
