Your link is not about children so of course it’s dominated by homicides and suicides.

Since around 2017 accidental children deaths from guns have been comparable to car accidents: https://www.nejm.org/doi/full/10.1056/nejmc2201761

The main difference is that cars are not made for killing, they’re made for transportation. Guns are made for killing. Thousands of children die every year so grown men don’t have to be scared of noises at night.
