Is YouTube blocked in the EU? Let’s assume it’s turning a profit there, then start wondering how. The obvious answer is that monetised videos generally have a subject, and advertisements can be tied to that subject.
I don't think Google has ever released the numbers on how many people have opted out, one can assume it's not 100%.
And you are clearly tracked across Google services at least, as anyone who has ever google something shopping related, then viewed a youtube video can tell you.

The obvious answer to me is that not everyone opted out. Businesses generally want to make money, collecting data clearly made them more money, or they wouldn't have done it. Now they make less on those who opted out.
