So I'm looking at this non-inverting Op-Amp

Trying to understand how Op-Amps work.
It seems rather strange they're saying no current flows from + to - because then how does the current from Vin spreads through?
After all, there is a infinite-resistance resistor there that blocks passage, from my understanding. As such:
