No, it's much simpler than that. Tracks and pads have a clearance value. If something gets inside that clearance then the error is generated. Sometimes you have to zoom in a long way to see the problem.
I find that this most often happens when a track turns around a pad (en-route to another pad) and the track just clips the clearance zone of the pad. You HAVE to have the clearance values, and they can vary depending on PCB production houses. It's up to you to set them to at least the required minimum value (whatever that may be), then to lay out the PCB without violating the clearance zones.
