First, just from a "danger" standpoint - more people in the EU die from heat than from guns in the US. And roughly 8 times more people die from cold than heat in Europe. So, I would say, that we live in an environment where our neighbors are armed the same way you live in an environment where you're often dangerously hot or cold - i.e. we get used to it.

Second, you can walk or drive on a street. Every passerby in a car could kill you if they wanted to by colliding with you. It rarely happens. Stand next to a tall ledge or overpass with crowds walking by and watch the teeming masses - you're unlikely to see any of the thousands of people walking by leap off to their end. Similarly, in life, even though basically anyone could kill you, it's very rare to encounter someone who is in the process of ending their own life, and killing you would basically end, or severely degrade, their own life. Almost nobody wants to do it.

Charlie Kirk is/was kind of an extreme example. He said many things that severely angered hostile people. He went into big crowds and said provocative things many times before being shot. I think in most situations you have to push pretty hard to get to the point where people are angry enough to shoot at you. If you can avoid dangerous neighborhoods and dangerous professions (drugs and gangs) and dangerous people (especially boyfriends/husbands) then you are pretty unlikely to be shot and you benefit from being able to carry guns or keep guns in your home to protect yourself and your family.

For one example, consider the "Grooming gangs" in the UK, where thousands of men raped thousands of girls for decades with the tacit knowledge/permission of authorities - and despite the pleas of the girls and parents for help. Such a thing could be handled quite differently in a society that was well armed. If the police wouldn't help you, you might settle the matter yourself.
