Normally, based on your description on her car damage place and yours, it appears her car was driving straight, she either didn't see your car, or she thought she could make it before yours coming out. It could be your car backing out too fast and hit hers. To be honest, it was your fault, but since it was in a parking lot, you might have a chance to get away with it. But if she reports to her insurance, her insurance will contact yours and your insurance will pay her most likely, because the damage place tells everything.

One time in a resident area, my wife was driving straight, a car was backing out fast and hit her car in rear quarter, at the end, the other insurance paid us.
