There's no evidence to support your sentiment. There is however ample anecdotal evidence that says people don't care. That evidence is manifested in app activity. Out of the top 10 apps downloaded, 4 belong to Facebook (Nos. 2,3,4, and 6).
https://www.businessofapps.com/data/most-popular-apps/ To say the average user doesn't know the extent they're being tracked would be a stretch. People know FB tracks the everlovin' snot out of them. It's the same thing with the popularity of Google's apps. People generally don't care. Their calculus tends to be: "I get what I want, they get to push ads that I can ignore." Win-win in their eyes.
More importantly, they generally don't care about privacy anyway. They lay bare the minutiae of their lives in excruciating detail on a daily basis. They do it on social media, in games, and in other online content.
If the only consequence of tracking is personalized ads, privacy advocates are going to find a hard time convincing the average consumer of the benefits of their way of thinking.
