That’s compatible with information theory. You have a piece of information, the moment you encode it (turn your idea into words) that piece of information is transposed to a little different piece of information, then the channel of transportation adds a bit of noise (depends on the environment, most often literal background noise), and then the receiver decodes the to a different piece of information (turn your words into an idea of their own).
Understanding this concept is an important communication skill. Information theory gives a bunch of tools to minimize the difference between the idea in your head and the perception of the idea by your peer.
You can add redundancy, aka say the same thing twice in a slightly different way.
Use questions to validate your understanding.
Have your peer use their own words.
Use a different encoding, aka draw a picture, a diagram, or use gestures instead of using language to communicate
