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

The Wii U wasn't portable. That's why.

I think you're wrong. At least, that's not what that store wrote 

"The games with "Wii U" on it need the Wii U handheld and aren't compatible with the Wii console alone"

So if the Wii U was named Switch instead you think it would sell gangbusters?
