Is Yarros taking over SJM (and male fantasy authors) in the fantasy department?

New York times released an article recently saying that Rebecca Yarros is the fastest selling adult author in the last 20 years.

SJM, Sanderson and Martin have been selling more copies per book, but I'm curious if Yarros is becoming the best-selling author in the genre (after Rowling), including male fantasy authors? Onyx Storm just came out, so it's too early to compare it to their books.

What are your thoughts on this achievement?
