Noooooo it just means that she grew up with Islam culturally because her parents are Muslim.
let’s say someone is born into a catholic family, they’ll grow up being catholic but once they have a thought and mind of their own they would leave if it doesn’t fit them and what they believe in. They would still hold a few catholic beliefs (like not having sex before marriage, being nice to those around you etc etc) but they won’t go to church or go worship to Jesus Christ and believe in the 3 holy spirits you know?
