Elvis worldwide album sales are not easy to know but he’s number 3 in the US with 146,5 milllion albums units sold. My guess is that he would be second to The Beatles in worldwide sales
The mathematical expected sales value of these 101 packages is 139,5 million
Presley has a further 7,5 million sales of EPs certified that fall under the albums all-time list of the RIAA, bringing his units tally to 146,5 million
