Matt Piscatella is an NPD employee who regularly shares/comments on their monthly video game sales charts. He’s basically just talking about the survey his employer does.
These things are “biased” in all sorts of ways, even in the way the data is collected. What if women are 80% more likely to answer phone surveys? 70% more likely to answer email surveys? That’s going to hugely change the results.
While mathematically sure you might be able to use a sample size of 10k to extrapolate out, I don’t think you can in this instance.
