This was always going to be the case. Google benefits from having a direct relationship with the customer, meaning that consent is relatively trivial to get. None of these third party tracker companies have that relationship, so rely on securing opt ins on a piecemeal basis. This is why a large number of the third party tracker companies all shut up shop in Europe in the months before GDPR.
If I go to a random website and they serve third party google ads, I don't have a direct relationship with Google in that scenario. It's not enough to say that because I have a gmail account I consent to being tracked all over the web on every website.
FWIW - ‘tracked all over the world on every website’ also comes with some significant caveats.
