You ain't shit 

= You're nothing.
However, 'you ain't shit' isn't necessarily an insult. You can comfort someone by saying that they are not shit.
You ain't shit vs. You are shit is definitely not the same. 'Ain't' is a general negation vernacular term.

FuckBoy : I cheated on my girlfriend and I don't even feel guilty haha
GoodMan : Really? You ain't shit, dude! (insult)

ain't shit nigga 

A nigga that ain't about shit. A deadbeat. Will never amount to anything and has no purpose in life, at all. And this applies to all ethnicities.

"We slept together and I haven't heard from him since."

"Girl, that's because he's an ain't shit nigga! Don't worry about him... move on!"
