What do you have against Michael Jackson and Thriller?
And why are you obsessed with having a White Male Guitar Rock Band outsell him and it?
That said, OTL, according to the RIAA, as of 2018 Thriller is no longer the best selling album of

Their Greatest Hits (1971-1975), by Eagles.
Mission accomplished.
And all it took was googling: best selling records of all time
Which is one of those searches that google fills in for you when you start typing.
