What do these lyrics mean??

Kid Ink - Big Deal

“back when we was living off fillet and fish meals,

young n***a came up hit the windmill,

See you playing at your heart, ima win still”

i tried genius lyrics but it wasn’t up 🤣🤣

does it mean his ex S.O. is playing with his feelings but he will rise above it or something else?? Thanks!

it’s an analysis i have to do for my Arts & Culture class haha
