I think you need to consider the difference between a browser, and the web dev tools that come with a browser. Let me put it differently, lets assume chrome has 10 billion users. Out of all those, how many do you think actually even know the dev tools exist? 10 billion? 1 billion? 100 million? No. More like 1 million.
Please take some time to consider what I'm saying to you.
