I don't think you know what the word "literally" means. Buble and especially Adele didn't have *literally* no promotion. Adele's had several concert specials, many HUGELY high-profile televised performances, and she's appeared on lots of talk shows. That's not "literally" no promotion. It may be less promotion than, say, Katy Perry, but it's not "literally nothing." That's an absurd statement.
I think successful pop stars get more money in the end because they get more lucrative endorsement deals and they can pursue other lucrative business ventures. Successful AC stars usually get most of their money from just their music.

Yes, but I'm talking about THE MONEY combined WITH the effort promoting a pop artist in retrospect to someone like Adele and Buble.
