Spot on, except the $450M part. According to a tweet, she might had got that number by adding up all copies sold according to VG Chartz and x by $60. It calculates pretty spot on. Problem is not all games are sold at full price and VG's sales chart for the series includes a subtotal row which she included which doubled her sales count.
So not only is she a liar going on social media with out of context tweets, but she cant even read a sales chart right. Also, retail $$$ means nothing anyway. Whatever the true number is, you can chop off 30% due to the retail cut. The remaining amount is what Nintendo/Platinum's sales are to wheel and deal with.
Feel bad for Nintendo. Imagine negotiating with this kind of person.
