Google Search Console: Clicks on Queries vs. Pages?

I have a small site that only gets a few visitors from Google, but I'm a little confused by something. For the last week I had 8 clicks, which (if I understand correctly) means 8 people clicked on links to my site from Google.

If I go to the pages tab I can see which pages garnered all 8 clicks ... but on the queries page I only see 2 clicks. What I don't understand is, where did the other 6 clicks come from? I would understand if I had hundreds of pages with tons of clicks, and Google just didn't show the small ones, but my queries page is full of 0-click rows.

Is the search console somehow referencing clicks from non-Google sources? Or is it just not showing me 75% of the queries that resulted in clicks, even though I have nothing else for it to show?
