No doubt, he did things that are not done in the past (regularly take and make "bad" shots, ie making bad shots good shots) because he is an elite athlete in human terms (but regular, not-overly athletic in NBA terms), and dedicating on one craft. Jordan did it with his turnaround, Magic did it with his passing, Shaq did it with his low post game, Hakeem did it with his low post game, Curry is just doing it with his three point shooting.
It's a skill he attained because he worked hard on it, and that he has the base athleticism and skills for it.
But to say that no other person in the history of man kind would have been able to do what he did regardless of cir stances is hard to believe.
