When you're poor and child-less, you can still sleep in on weekends, watch Netflix/game all day/night or whatever other (cheap) hobby you have. It's even possible to do a decent amount of travelling on a very tight budget these days (low-cost airlines, couchsurfing...). All things considered, today is not a bad time to be a poor person in terms of being able to have fun.
I think even for middle class, the main cost is actually the time rather than the monetary cost.
But I do agree that opportunity cost is the right framing.
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.
I understand procrastination for sure, but the idea that someone would avoid having kids to do the above is absolutely bizarre to me.
One thing which I kind of regret about having children relatively late in my life (although I wasn't that much older when I had my first than you are now) is that I won't be there for them (and potentially grandchildren) as long as I wish I would be, esp. in good health. A depressing way to think about this is that every year I've enjoyed the freedom before them is a year I'm not going to spend with them.
In any case, it’s just a plain fact that some people don’t desire to raise a child. Many, probably most, do, but many don’t. Personally, I’d pick the video games. Heck, I’d pick nothing as a preferable alternative to raising children. Not everyone considers it a positive.
crazy thought i know.

It’s the opportunity cost of having children. When you’re poor, it’s not changing what you can do with your life. You were never able to go to dinner or on vacation. When you’re wealthy, you can afford to bring them with you, or better, pay somebody to watch them while you’re gone. The well-off middle class needs to weigh completely changing their lives.
