If that 10k is representative, that should give a very small uncertainty interval, less than 1%. You can get 95% confidence interval with only a few hundred samples depending on the standard deviation, so 10k is actually massive. It’s pretty standard statistics, here’s more info on how it’s calculated.

I know jack shit about statics, or this study, but 10K participants seems more than solid if it’s proper science.
