I don't know what the percentage is, but having a school within walking or biking distance is definitely not uncommon in US suburbs. At least in the areas I've lived (in multiple parts of the country), schools are generally built close to large neighborhoods, and have dedicated infrastructure to help kids walk to school. Grocery stores are less likely to be within walking distance. But then, even if I could walk to a grocery store, I'm not sure I'd want to, because I would be limited by how much I can carry back, which means I'd have to go shopping more often.
Conversely, I have traveled to Europe and Japan. At least in the areas I went to, it didn't really seem any safer for kids to play outside than many parts of America. Yes, public transit was much better, but there were still lots of cars on the streets, and there were areas that weren't very pedestrian friendly. And in some cities it was quite difficult to find playgrounds. I don't doubt that there are places in Europe and Japan where kids can play outside without worrying about cars. But such conditions are not universal.
None of the US comments are true in the large areas of Georgia and Arizona that I'm familiar with. Sidewalks are very uncommon. One side of street only, if even there. Which is problematic at multilane intersections. Then the kid has to cross twice on each side. I actually managed to get a crossing light installed on my kid's bike route to school by complaining to a city council member. There are traffic jams at every school for drop-off/pick-up. Drive through the quite nice looking housing developments on weekends/holidays and there are zero children out and about. My wife and I think that's very sad.
That said, my kid rode a bike to school from 5-10th grades in Arizona. She was the only kid that did that.
There are about 7 grocery stores within 5 miles of my suburban house. I have never seen anyone walk/bike to any of them. (I look.) If you tried to you would spend quite a bit of time navigating parking/road infrastructure where the drivers clearly believe is their entire right of way.
In Mexico you would think it would be much worse, but it is light years better. Kids take care of getting themselves to school in Paris, from what we have seen.
This idea that "unless universal, the claim false" is... not helpful. As a family in suburban US we did the bike thing. It fucking sucked.

I have 2 (soon to be 3) grocery stores within a 8-12 minute walk of my very suburban home in my master planned community full of tract homes. I see some people walking to and from the store occasionally and I’ll walk there on occasion in the winter when the weather is nice. I just don’t understand why I would spend 20 minutes doing something that can take me 3.
Yeah, the American comments here seem to boil down to "technically I could walk to a school/store/cafe if I wanted to (but it's quite shit so nobody does) so it's basically Europe and Japan" and think that's comparable to a town of people who walk around daily and bump into neighbors while fetching milk from the local shop. Even Mexico is like that.
If we swapped some of this cope energy with a push to change things, maybe we wouldn't have to burn our vacation time to fly across the world to walk to a cafe on a pedestrianized street.
I've driven around a lot of dogs sleeping in the street in Mexico. Everybody else does too, claro que si. Now imagine a child. No one is going to threaten that child.
Assholes exist everywhere in the world but I would walk across an ungoverned street intersection in Mexico sooner than cross your average 2+lanes each fully lighted intersection in the US.
Edit: and so I now add, that that's what it means to bump around with your neighbors, near daily. Humans seem to need the street life of a busy neighborhood with pedestrian traffic toward the local suppliers of the banal things of daily life, before they retain the idea of the sanctity of humans when they are thinking more abstractly.
The contradiction of course is WW1 and WW2, which happened in countries all adhering more or less to these characteristics.
So I dunno. Maybe we're all fucked in the end, and I at least will indulge my family in the residual beauty before the inevitable next societal upheaval.
