In my experience, you're dramatically overestimating how many people really understand what a browser is, what IE is, or can disambiguate between Chrome and Google.
"Everyone" wasn't the literal everyone, "everyone" is the group of people that buy a Windows OS and install another browser. Those people know what a browser is.
Maybe I misunderstood, but I was replying to your overall message about:

About half of people using Windows continue using IE right now. So, "everyone" and "average" definitely refer to a lot of people who have absolutely no idea what any of us are talking about in this entire page of comments. It's so easy to underestimate how little truly "average" folks understand or care about these nuances in the real world outside of a few tech bubble areas.
I have an excellent example of this.
Despite having both Chrome and Firefox installed on my home desktop computer, my wife continues to use IE 11. Even with her own profile for Chrome, and using an Android phone with Chrome, she still sticks with IE for some odd reason.
