It does not.

It uses probability to predict words that belong near the other words in your prompt. It's a more powerful version of the suggested words at the top of your phone keyboard.

You could write a sentence or two using that, but it will quickly descend into gibberish.

It does not "understand" what you wrote in any way. It just has a heuristic that shows the word "Mom" comes after the word "Your" with a high frequency, so that's what it's going to output.
