Its not so much a statistic as just a generally common thing. The main cast are the most commonly appearing characters and the events of the game/movie/episode/novel largely revolve around them. If they aren't these things then they are supporting characters.
That's not a clear definition, honestly. Toad and Peach can also be considered supporting characters before they actually become playable in later mainstream games. If the others have to stick to that role, they may provide "support" more often whenever they should.

And even so, Daisy has more of a claim than Waluigi
Waluigi hasn't been in any mainstream games, while Daisy has Super Mario Land

And Waluigi was not even in Mario Kart 7.
Uh... that's abit like pot calling kettle black. I can only say, judging from their actual roles, Daisy could have more apperances with Peach while Waluigi isn't always around, unless he goes to Warioware.
