My ability to succeed in approximately deciphering an arbitrary sentence conveying meaning A is lower than my ability to communicate that approximate meaning myself. The odds are made much lower if communicating with a new person not already aware of my exact vocabulary. Of course, I can decipher much fancier sentences than I can produce (especially in a controlled environment as I originally mentioned). My produced sentence will be much more awkward than the sentences I can decipher, but it will work. From my perspective, this makes listening harder than speaking - I will not be fluent in a language until a decade of practical use, so the only metric that matters to me is whether something had practical application and acceptable understanding. In that sense, removing parts of a sentence you can't produce before you say it still passes as a success, but not understanding anything or most what a person is trying to say to you is not. Most people are not able to sufficiently simplify their speech as they do not know what or how you have been taught. If you are already able to have the meta-conversation needed to inquire about and discuss meanings of words and sentences comfortably, then you are already an advanced speaker. Note that this is very subjective. I am expressing my current state of learning as it is, and claiming that this is wrong is silly. On the other hand claiming that you will experience the same would also be silly, but it's none tell less worth sharing experiences.
