So far I believe each person on this planet has at least heard of Marvel superhero movies, perhaps even watched a few of them, and no wonder. Movies are spawning now over 20 titles and they are not really released as events described in them.
Throw into mix TV series and you can get confused pretty fast. Now it was officially stated that all TV series that were released before Wanda vision is no canon in Marvel cinematic universe which simplify thing a little but there are still series that are.
