As I understand during A/B testing users are randomly shown slightly different layouts/visuals/UI/something and after some time the company decides which one performed best and uses that in the future. Is this correct?
Then how do they determine which is better without asking the users? How does Youtube know that I hate it when they don’t show me when the video was uploaded when I watch videos anyway, since that’s why I went there in the first place?

In the case of YouTube, they don’t care if you like the visual change. They care if the visual change causes you to watch more videos, so they can monitor that metric without asking you.
