TS,
Saw my cousin in Pak a few weeks back. She was born and raised there. She’s been married for two years (got married in her mid-twenties…so she was older than your daughter)…and MashaAllah se, she’s very happy. She now has a son who is almost a year old.
She herself tells me that she learned cooking/household management after marriage. Her family had a servant, she was busy with her education and job, so never really learned cooking before marriage. After marriage, she adapted.
I know of other friends and cousins who learned these things after marriage.
People can usually adapt to situations. You adapt to a new school…new job…new home, etc. It’s a bit challenging in the beginning, but as time goes by, you start adjusting.
I know examples of people who…when living with their parents were very spoiled (didn’t have to do that much housework). But then they moved out…or moved to college and lived in a dorm…and slowly started cooking their own food/cleaning/doing their own laundry, etc.
Your daughter will be fine 
If you’re so worried about her, gently encourage her to start cooking. Maybe you can tell her to cook one dish a week. Perhaps on the weekends. One week she can practice vegetarian…another week a meat-dish…another week a desert. Etc.
