That depends on the culture and the method of distribution, many cultures that practice oral history did have widespread interest and access to it and an understanding of how their culture fit into the broader scope of the world to some degree, though the way they understood or related to it might differ from culture to culture (some cultures tie their history to places, or names, or events, or people or seasons, etc). As another example, the Romans are well known for their prolific historiography and many of their surviving texts are still referenced to this day. Look up Pliny the Elder and Pliny the Younger, who were just as well known and respected as historians at the time as they are now. While written works such as the Encyclopedia Natural History (written by Pliny the Elder and believed to be the first encyclopedia) would often be released to the public to be copied and spread, they would also often recite written works orally so illiteracy wasn’t as much of a barrier as you’d think. Oral history is a lot more important in providing a record of a culture’s history as well as making that history accessible to others than a lot of people think. It was important in ancient Greece as well, and is a huge part of many other cultures around the world including many indigenous ones. It’s also not as inaccurate or unreliable as some people might think, as there were many methods these cultures used and still use to preserve the accuracy of their oral history as it was passed down from generation to generation.
Now in terms of awareness, obviously there was propaganda and rewritten history going on back then just as there is now, but it’s not as if none of the citizens would have been aware of that. One of the papers I wrote for a class about the importance of comparing primary sources featured 3 different accounts of what Athens was like and the views people there held at a certain point in history from 3 different people of varying social and financial status, and there was absolutely awareness of that sort of dissonance between what their government claimed and what the reality was even among the more common folk. So I would say they did certainly have a significant understanding of how their culture fit into the broader scope of human history.
Stuff like this is part of why I dropped out of multimedia production in college, I only enjoy that stuff as a hobby for myself, doing it for other people is a creative nightmare lol
