Mother Compares Me With Cousins & Friends

I may sound silly.
Ever since this "Stay-at-home" lockdown implemented, my mother is on an spree comparing me with my father's sidecside and her friends children who are successful & elder than me.
Irony is she doesn't compare me with her brothers children or sister's.
Every single time when I call her or she calls me she picks a topic on other's children who own a expensive car or house
I tried to ignore but this is been going on for 3-4 months I reached my threshold.
Told mom why you always talk about others , let's talk our own things.
She got mad told "what else is there to talk, vera Enna irukku pesaradhukku?"
I'm upset thinking 'why she keeps telling others have this that's
1)They are far older than me 40s, I'm still in early 30s
2) actually they're not great with thier parents. Some don't even call thier parents to US/overseas. No gifts,phone calls are also made from parents. My aunts uncles tell me atleast you call once a while.
3) Same goes with kids they put in 3-4 rating school to save money on rent/house. They tell me why are you wasting money on kid?
How is education a waste of money?
I slowly starting drifting from toxic & money minded people. To save myself
I say hi - bye wish on Diwali new year.

How can I make my mom understand, what she is doing is wrong.
My dad understands well he never ever talk about others. We always talk our own things.

Every one's life goal is different. My mom fails to understand. My MiL also does this with my husband sometimes.

Just a vent
