The gender difference is huge though, the nongaming cohort had 288 males and 840 females while the gaming cohort had 372 males and 307 females.
Also, I'm a bit confused why they just dumped anyone with between one and three hours of videogame playing a day.
Maybe you saw it in the text but, "This threshold was selected as it exceeds the American Academy of Pediatrics screen time guidelines, which recommend that videogaming time be limited to one to two hours per day for older children."
The thought process I can sort of imagine is that the tests are fairly costly and the hypothesis they're testing is that more play than the official recommended limit should decidedly give detectable impairments to cognition. (Seems they could have rejected that, if they'd had comparable groups in the first place. Now I'm not sure what it says)
Screen Time Survey
This threshold was selected because it exceeds the American Academy of Pediatrics screen time guidelines, which recommends that video-gaming time be limited to 1 to 2 hours per day for older children.

Given infinite money I think many of those parents would send the kid with nanny if needed or whatever to organized sports, piano classes, etc.
Source on that? Video games (console or pc) is very expensive and not something low income folks can generally afford for their kids.
Of course, without video games either, kids will find a way to have fun regardless. My grim apartment complex still had kids kicking around a soccer ball or riding bikes in the parking lot.
Video games are the cheapest form of paid entertainment for the amount of time that a single purchase occupies.
Despite their audience being extremely price sensitive (which has nothing to do with socioeconomics, just consumer expectations), all stakeholders recognize this and extract value in other ways.
Just some anec-data. I did not have any consoles growing up simply because we could not afford them. Eventually we got a single very old very slow machine that was shared among the family. I know a few other people in the same situation (usually 1st/2nd generation immigrants). Thus in my mind, video games are luxury products, which are not affordable to low income households.
