In 2020, two thirds of Google searches ended without a click
It should be noted that Google (applies to other search engines) searches aren't just web searches anymore. Rather Google is frequently used as knowledge engine similar to WolframAlpha albeit not in that level (yet). Specifically a click-less Google search can be:    spell checking (term "wrng wrd")
    dictionary (term "define word")
    word translation (term "random in greek")
    calculator (term "1+1")
    unit conversion (term "1m in ft")
    weather (term "weather tokyo")
    sport scores (term "uefa scores", or ufc, nba, ...)
    map instructions (term "instructions to nearest city")

For fun search any of the aforementioned terms alone (besides the first one) and with term mentioned in parentheses. Also lots of searches return card information (e.g. "spell checker" or "Issac Newton") or snippets which are seen when searching for instructions. That is when searching something encyclopedic where one-line summary or some simple instructions will suffice means someone will not go ahead and open Wikipedia or any other site.
