Not generally true. Many airplanes have nosewheel steering that has no connection at all to the rudder pedals.

Not true. I use differential thrust all the time in landing in strong crosswinds. Also departing icy runways in a strong crosswind. Been known to use it on the ground when I've found my nosewheel sliding along on ice and snow.
