They've already been told that she isn't though. Her fruit just keeps her from aging.

Latent observation haki would certainly explain how Usopp has always been an excellent sharpshooter and how he seemed to have such an excellent eyesight.

It's like saying Zoro is only a good swordsman because he had latent Haki the whole time.
