What's required to awaken the Rinnegan is Hagoromo's chakra. Since Indra and Asura's chakras together make up Hagoromo's chakra, a transmigrant of Asura or Indra just requires the other transmigrant's chakra, but it's faster if one gets Hagoromo's chakra. Sasuke could awaken the Rinnegan right away, while Madara took decades because he had to succesfully mix Indra and Asura's chakras first.

Orochimaru's Cursed Seals are infused with Orochimaru's senjutsu chakra, but that doesn't make Sasuke or any other Cursed Seal user a senjutsu practitioner. They don't mix natural energy with their normal chakra.
