A theme I've noticed in the comments, and in the public at large, is confusing learning history with learning to be an historian (or historical thinking).
During my degree, I obviously learned a great deal of history. However, a large portion of my time was spent on context-building, and attempting to understand sources on their own terms and to contextualize them into the broader world around them. For example, to study the famous historic period foo, you must first learn something of the period before it, bar. It's also important to understand its society and culture, as well as those of a place's neighbours (you can't learn English History without learning some French history).
It felt less like a degree in "history", and closer to a degree in context-building. This, in my mind, was the greatest value of it, as it wormed its way into my brain informs how I view new topics and ideas. It's something I've noticed is absent for many smart people when they talk about history specifically (although they may be excellent at it in other fields).
A high school history course's purpose is to teach a base set of facts, as well as to teach children the state's narrative of its own history (for better and for worse). These cirriculums are usually written by hsitorians to fulfill the state's needs. Youtube videos and podcasts contain many facts, but their interpretation of the sources lead to poor understanding of the topic, and factually incorrect statements (since they're lacking broader context to understand them). Both of these have flaws, and lead to individuals "learning" something that may be incorrect, or that they have misunderstood to the point that they have learned very little.
I suppose that the point I'm trying to make is that learning about history != historical thinking, and a lack of historical thinking can inhibit the learning of history.
As a side note, the Revolutions Podcast (and by extension I suppose the History of Rome, although I haven't personally listened to it) is the only popular history media that has actually impressed me with its methodology. /r/AskHistorians has a tendency to be excellent as well, albeit with some caveats.
