Samples of pressure (or displacement, minor phase difference), so kinda yeah.
How one gets so much variety? By sampling it really often. If you sample it 40000 times per second you actually get the full information for all pitches that are between 0 and 20000Hz.
If you don’t sample it often enough you don’t get all the information needed to store the sound. So yes we kinda indirectly do capture all the different pitches.
