I prefer to state it as power (watts) kills. To be truly dangerous you need voltage to overcome the electrical resistance of the human body and amperage to cause damage and burns along the way. Either one alone is relatively safe.
(And then there’s a whole other discussion to be had about frequency. DC pretty much only causes damage by burning tissues along the current path. Low frequency AC is especially dangerous because it can interfere with and disrupt nerve signals, causing muscle convulsions that force you to grip tightly onto the source and potentially disrupting the heart’s timing if it passes through the heart’s separate little nervous system. But at a certain point (around radio frequencies), higher frequency AC stops being as dangerous because the frequency gets too high for nerve cells to react to, and it goes back to only causing damage through burns, like DC.)
