How exactly does DNA Polymerase differ in function for Mitochondria and Plastids

Question

I have come across a few things in biochem that while DNAP3 takes care of DNA replication in Prokaryotes, DNA polymerase elipson and delta take care of Leading and lagging strands of DNA in eukaryotes.

I can’t understand that if Mitochondria is of X cell (X being any cell), shouldn’t it also have the same DNA as the X cell? In that case why does it need DNA polymerase Gamma?

And on that note, do plastids have some sort of DNA polymerase abnormality like that of DNA in mitochondria?

I have googled and tried to read up on them but at one point it gets really convuluted, so a simple definition would help a lot.
