This is a plea deal, no one is going to plea to the maximum, which in this case is 20 years. The punishment can also be a fine [1], which may be fitting if the goal was profit from a YouTube video.
When news articles mention the maximum, especially in headlines, it feels a bit misleading. It seems there's a decent chance there is little or no prison.
