Because he never experience Prime Hiruzen, he just like the others only knew the fable of Madara and Hashirama. In Hiruzen's time there was nobody at all who could beat him or contest him as Hiruzen never had his own Madara to fight. Madara also knew Hashirama really good(just like Hiruzen but still) Dan is only about Jiraiya and Tsunade's age so he couldn't know anything about Maddi and Hashi anyways, only the fable.
