One goalpost at a time please. 90% of users in "a given country" is not the same things as saying 90 percent of all users. Unless that country is so important that it's everyone, and again you needed to test that your product is usable in the first place. And even so, while there are a lot of countries and languages, a collection of tests in all of them, which is all it takes for these examples, is not "big data". Again you are crediting analytics for things that people were fully capable of and responsible for doing in the days without traffic data. I realize it is great for the resume and sounds sexier to do "analytics" as opposed to just basic software testing (you should see what people are calling "AI" in other industries these days). And I'm certainly happy to agree that analytics has some value, say in improving wording and stuff that a single instance won't tell you, but again these aren't cases of that.
