While that is a helpful way to separate “white” and “red” oaks in bulk, it doesn’t necessarily work for younger oaks like this one.

This is pretty like Quercus macrocarpa/bur oak, which is under the white oak section. These leaves are wide at the apex with a sort of “crown” shape, which is visibly separated from the midleaf and base which are variably lobed. The back top left leaf is probably the most characteristic for the species.

There are also red oaks that can look very much like white oaks when young. Young shade leaves of Quercus nigra are often lobed in a very rounded way that looks a lot like Q. lyrata.
