There is a great difference between Voltage (Electrovoltaic Force) and Current (Electron Flow Quantity). Static electricity can reach hundres of thousands of volts, though the current is next to nothing. I have heard stories where people can be easily killed with a very low voltage, it was that they were in a situation where they were very conductive and could pass a great deal of current.
Even 1/10th of an Ampere can be fatal!
