In a parallel combination each circuit has the same voltage $U$, which can be easily shown with Kirchhoff's laws. But the potential difference between the two knots of the parallel wired part is nonzero. Therefore current flows, depending on the resistance (where the voltage drops) of the parallel-connected circuit (so that the voltage $U$ is the same in ...
Think of the amount of (molecules of) water in a hose. Does it change when we start pumping it around?
