Ping is, essentially, a measure of distance. When you exclude obvious issues like an overloaded router causing slowdowns ping is the time it takes for your packet to reach a destination, be processed by the receiving machine and returned to you. The further away the target is the longer the ping is because you not only have travel time but you also have additional processing time by each router the packet hits along the way.
A 1ms ping is completely impossible to hit even the nearest server outside your isps network because it takes several hops before it leaves your isps network and those hops add several ms each time.
