I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

    Its not sure how it exactly works, but most probably this captcha processes a lot of data like your mouse movement, mouse click but also your browser fingerprints, search history and ip. You can actually get ‘traffic lights’ test from this clicking button captacha if You have privacy protection in place, such as using brave, tor, firefox or mullvad browser and/or vpn, pluse some privacy browser extensions
