exploring Chess Insights tool

I don't fully understood the Chess Insights tool. Am looking into it right now.

One of the presets is "What is the Win-Rate of my favourite openings as white?". In that I'm seeing a list of 12 openings with the win/loss rates. I'm very confused by this. I always open the game with E4. That's it. So what are all these other openings? They're certainly not mine.

Fyi: en.wikipedia.org/wiki/Encyclopaedia_of_Chess_Openings

e4 is not an opening ;)

If you start with e4,then many openings can occur in your games e.g. French defense,Russian game,Italian game,Sicilian defense,Caro-Kann,Philidor and many others.There cannot be only one type of openings you have to face sometimes.
