No, you are wrong.
Being attracted to/having sexual urges towards children is pedophilia. It doesn't matter if it's a real child or if it's a good 3D render or if it's an anime character. It means that person suffers from pedophilia at some level.
The fact they don't act on it with real children has nothing to do with it. That is a separate issue called child molestation. THAT requires a real child. Pedophilia does not.
