If exclusives sell consoles, how come the Wii U failed? Also, why are few youtubers saying exclusives sell Switchs/PS4s but not Xbox Ones?

I mean,even on the exclusives department the Wii U kinda lacked. The console came and go and it didn't received a Fire Emblem, an main Animal Crossing, a Metroid, an main Kirby,a Luigi's Mansion,the 3D Mario was a sequel to a portable game and not the open worldmany were hoping, it only got one Mario Party,the Zelda and Paper Mario released at the very end of the console life. It had pretty good exclusives on it,but many Nintendo franchises went missing on the platform.
