I have no luck with this vs I ain't got no luck with this

What is the difference between “I have no luck with this” and “I ain’t got no luck with
this”.
I mean…when do we use “ain’t no”…“ain’t nobody”
and on what basis…as far as I know…ain’t and nobody…both sound in Negative…already.
then why ain’t no…

Thanks…

Have a Nice day…!!

‘ain’t no’ is incorrect grammar. You may hear it being used informally, but it is not correct usage.

Thanks Beeees…
But I have also seen people using taglines…like"ain’t no sunshine"
So these are also wrong ?
Then when do we use “ain’t” ? or how ?
In correct English…

Thanks again.

‘Ain’t’ is very informal.
‘Ain’t no’ / ‘ain’t none’ are very informal and also incorrect, but widely used.

‘Ain’t’ means ‘are no’.

There are no vegetables on the shelves =
There ain’t vegetables on the shelves =
There ain’t any vegetables on the shelves (another variation) =
There ain’t no vegetables on the shelves.

Only the first two are strictly correct, and only the first is suitable for semi-formal or formal usage. However, all will be heard and used regularly, including usage by native English speakers.

‘Ain’t’ also commonly and incorrectly replaces ‘is no’, as you see in ‘ain’t no sunshine’.
There is no sunshine. =
There ain’t sunshine. =
There ain’t (isn’t) any sunshine =
There ain’t no sunshine.

Thank you so much for the help…
