More are injured than are killed, and just because you survive doesn’t mean that you fully recover. I would consider someone injured in a mass shooting to be fairly affected. I would also consider relatives of those injured or killed in a mass shooting to be affected. Maybe it’s a stretch to say that the employer of a person who had a relative injured in a mass shooting is affected, but, due to the shooting in Dayton last weekend, I was down an employee most of the week.
As to the others, we are working on smoking deaths, and there’s going to be some lag on that. Even though I quit smoking several years ago, it is not unlikely that in 20-30 years, I’ll be counted as a smoking related statistic. Would that mean that smoking is still a problem, even if there are no smokers anymore? We kicked smokers out of pretty much all enclosed public spaces, we taxed the hell out of cigarettes, and forced the tobacco companies to pay for anti-tobacco ads.
Whenever I drive, I assume that everyone else on the road is trying to kill me. I take precautions, I drive carefully and defensively. I take active steps to lower the risk to myself and those around me. There are also cops out on the road that I see everyday, and they too are tasked with working towards making the roads safer.
We are focussing on those things, and it is working, both at a society level and at the individual level to decrease your risk of being harmed by them.
Unlike those other dangers, a shooter comes with no warning. Especially in our open carry culture, a shooter can walk right to their target without anyone batting an eye until they start pulling the trigger. There is nothing you can do to lower your chances of being involved in a an active shooting situation, except, as you point out, never leaving the house.
Those other dangers you mention, those are things that we can prepare for, we can work to prevent, and we do work to decrease their effect. For a shooter, there is nothing that can reasonably be done on an individual level to lower your risk of being involved in one, and there is nothing being done on a society level either.
