Madara wondered if Obito could awaken the rinnegan. However, Madara could've possessed the requirements for decades before awakening the Rinnegan (the timeline isn't clear enough on this). Obito may simply not have been old enough. But as i mentioned above, Transmigrants seem to have vastly improved odds of awakening it. That doesn't rule out regular people can't, but it's improbable enough that it never happened.

Sharingan originates from Indra, so having Sharingan means that you have Indra's chakra, or some of it. Hagoromo made it clear that their chakra's are highly scattered, but eventually someone will have enough pieces to create a transmigrant, which seems to reset the cycle. Thus, being a Senju/Uchiha means that you have a piece of Ashura's /Indra's chakra. Transmigrants however have far more of those chakra fragments and thus far higher odds.
