She made a guess at the age. It’s says so in the article. She knows she was very young. Maybe not quite as young as five, but she knew early.

She made a guess at the age. She didn’t say it absolutely happened when she was five. She was just taking a guess at the age and feels like it was when she was very young. I get what you are saying, I thought the same thing, but when I thought about it I realized that she said she wasn’t sure about the age.
