Search Engine Result Page (SERP) ads shown on Google itself are far more valuable than display ads that get shown on random websites. Google has been slashing payouts to those sites for over a decade. More recentlt, they've been slashing search impressions to those sites as well. With search engine ads + Youtube ads + Play Store ads, they can probably cut out the third - party site ads business altogether and not miss a beat.
