Yeah, but I would think that humans are generally bad in "intuitive statistics", e.g. when drawing conclusions based on their observations. Of course most of this may come from our inability to observe accurately/objectively when not dedicating significant brain-power to this task.
When you say "a lot of people" you also presumably witnessed, interacted with, talked to, and watched, other people that do the same.
I can e.g. say "a lot of people have iPhones in NY" just from walking around in Manhattan, even though I never read any particular study.
Seeing people and seeing that many of which you see everyday do X is still sampling.
