I read that current flows in all available paths, so when (blue) current flows from the generator it will divide into (red) and (green) at point A.

Why doesn't the (green) current flow in all available paths at point B (flow in the opposite direction of red.)

My friend told me that current flows through the path with the least resistance but I read in google that some small amount of current will still flow through all of the paths.
