People who are mute still communicate. They're not merely listeners.
If you're not practicing output, you're not truly comprehending. Output, whether it be speech, writing, or signing, is how you get and demonstrate confirmation that you comprehend.

This also implies you cannot understand a language without people who can speak it to you. You can learn to read books without reading them out to someone who tells you what they mean.
Honestly, this doesn't even really make sense considering my own experience of going from not comprehending stuff like shows and podcasts to being able to almost completely understand everything being said a lot of times, without any real practice speaking to people. Unless you want to claim that I'm not actually understanding anything at all :).
