Not exactly "anyone can do this," but the first paragraph in the above link:

"The answer is an emphatic NO. In order to make good and useful contributions to mathematics, one does need to work hard, learn one’s field well, learn other fields and tools, ask questions, talk to other mathematicians, and think about the “big picture”. And yes, a reasonable amount of intelligence, patience, and maturity is also required. But one does not need some sort of magic “genius gene” that spontaneously generates ex nihilo deep insights, unexpected solutions to problems, or other supernatural abilities."

Nowhere in there does he claim he is not a native genius. Nor does he say that anyone can do what he does if they merely study as much as he did.

This is about whether any intelligent person can "do mathematics", not about whether anyone can be like Terence Tao, one of the most brilliant mathematicians in the world.
