Does it not make sense that the fatter tire will have more rolling

I thought this too, but I now believe that I was incorrect.

If you look at vehicles built for straight-line speed
(other than those where massive power needs to be transmitted to the
ground - definitely NOT bikes) be it soap-box racers to land speed record
assault rocket cars, the tires are hard and skinny to minimize rolling
resistance.
The narrow tires are more aerodynamic and can take higher pressures.
