Mario & Luigi, Paper Mario, Super Mario RPG, Yoshi, and Wario are separate because their games have a ton of original characters and ideas that aren't part of the main Mario line. Mario Kart doesn't really bring any original characters into the mix aside from baby versions of the characters. It's just mainline Mario characters in racing karts, sure the race tracks could be counted as "original content" but that's not enough to really warrant a new game section.
As for Super Mario 2? Most of the characters from that game (mainly Shy Guy and Birdo) are staples of the mainline Mario games. That game never had any followup that played in that style, so it'd be redundant to just make a section dedicated to that one game.
