here she quotes what I sent to her

That is what would happen if you caused clipping in a raw wav file, yes. But
that is not what happens when you use MP3Gain.
An mp3 file does not directly store the original wav data. Instead, it
stores a description of how to re-create the original wav data.
Pretend I wanted to send you a simple wav file-- 60 seconds of a 12 kHz sine
wave at 80% amplitude.
I could send you the raw wav data, or I could instead send you that text
description I just wrote: "Create a file that is 60 seconds of a 12 kHz sine
wave at 80% amplitude". It would take a little more work on your part to get
the wav file, but the data I send you is much smaller.
If you change that "80%" to "110%", then your generated wav file will have
clipping. But the clipped parts are not "lost", you just need to change that
amplitude field back down below 100%.
That's a very, very simplified version of how mp3 files work, and how
MP3Gain changes the mp3 data.
I hope that makes sense.
