Human beings vary in all kinds of ways, more than we generally expect, right down to the nature of our most fundamental fears and desires. Not everyone wants to have children, in the way that you do, and some people clearly want not to.

I doubt that anyone would prefer gaming to children because they hold gaming in the kind of profound esteem you feel for the task of "raising a literal human child"; more likely, they simply don't feel much of anything about having kids, or perhaps they feel some aversion. It's not hard for even a comparatively trivial activity you enjoy to feel more appealing than an alternative you don't actually desire.
