You're correct: Wired has hyped the original title of the article in Quanta Magazine: "A Path Less Taken to the Peak of the Math World". Any time you see the words "Math Genius" you should assume hyperbole.

If you like this kind of story, I highly recommend putting Quanta (https://www.quantamagazine.org/) on your radar and avoiding most of the tabloid-science articles in Wired.
