Who end up in charge...One possibility is the peasants recruit high level heroes to help in their revolt or ally with a powerful wizard
A peasant revolt could work in 5e, because 5e is written by people without much grasp of how violence works, what feudal/medieval times were like, or why a military unit is greater than the sum of its parts.
Most setting imply that the people are just Americans (or First Worlders) living in a interesting place. In reality, peasants/serfs lived badly; insufficient food, and poor food. They were the first to go hungry when there were shortages, they could not leave the land without their lord's permission, they were not allowed to own or train with weaponry. Illiteracy was universal, and most lived their entire (short) life within five miles of the place they were born.
When they did rise up, it was because they were desperate, and they nearly always lost (in Europe) because they were a bunch of worn-out, uneducated farm workers with improvised weapons. They did occasionally win battles against forces that were thrown together in the impression that one good blow was all that was needed, but sooner or later the powers that be sent in armored knights and professional footmen, and the peasants died in great numbers.
It was not until the musket arrived on the scene, simple and quick to be learned, that the peasants had a chance.
The best analogy for a peasant revolt is this: pick 30 people grabbed at random, ages 12-45. Put them on a football field facing the starting 11 from a college team of your choice. Send the refs home.
