You quickly learn what it does and go from there.
The technical side of it is kind of mundane. Yes the audio is a separate part of the 'file bundle' at a certain level, but some users don't really need to know/understand that

'Extracting' the audio part and 'converting' it to a new format could make both terms correct.
Just my thoughts
/it likely runs thru a convertor of some sort along the way, even though you are extracting just the audio

I largely agree. Only those writing the software likely need to know the details.

What I care about is that someone is being addressed very rudely for allegedly saying something he did not say.

The person said "convert a [YouTube] video file to an mp3 file."
That is perfectly correct and reasonable.

If the person had said "convert video to audio", as alleged, that might reasonably be considered illogical, though frankly forgivable as "a video" normally has associated audio. If we watch "a video" we normally expect that it will have sound.
