Sure. Except in the last three years that "frequency illusion" has been happening to me with a... growing frequency. About every 2-3 months, Facebook shows my wife an ad for some completely random shit we're sure neither of us searched for before or mentioned to anyone else.

There is great statistical power in these ML models, in many cases the "random shit" will become the topic of conversation due to shared social factors that can be predicted, you simply neglect to recognize all the times the modeling failed.
