Yeah that's just an exaggeration. He also doesn't know FTG. I think that statement can be interpreted as Hiruzen knowing the strengths, weaknesses and mechanics of (almost) every jutsu used in Konoha. Just like how Engineering professors in elite universities can't build each and every top-notch machine they teach about in classes. They can perhaps build some or most of them, but they know the principles behind almost all of the technologies in their respective fields.
