Wrong only one person other than the sage awakened the Rinnegan and that was madara because he had hashirama's cells but that doesn't mean only the uchiha can awaken it. both uchiha and senju can.. if hashirama were the one to take madara's DNA he would have eventually awakened the Rinnegan. same with Naruto if he is given sasukes DNA he will eventually awaken the Rinnegan
