It's also fallacious to look at numbers like "1000 / 30000 = 3%" and say that you shouldn't have to worry about getting electrocuted when handling electricity because it's only a 3% chance of dying if you get electrocuted.

That 3% number is causally intertwined with the fact that professionals take safety very seriously, and most non-professionals are afraid of electrical stuff and generally do try to take precautions around it, within the limits of their own knowledge.
