Is being claimed as a dependent worth it?

I'm 29 and live with my mother full time.

I graduated from college last year and they just sent my 1098-T.

I put it into my Turbo tax just to see if I would get a refund or credit with it (I have no income, not disabled)

It says I would get a $1,000 Refund.

 

Problem is, my mother wants to claim me as a dependent and thinks claiming me will help her in some way because she owes every year.

I haven't found much info regarding this and wanted an opinion.

Can she even claim me being as though I'm 29 and would it help her at all?
