I'm not sure if you are looking for just audio or audio and video.
I use this. mp4s.org/en1/youtube-to-mp4/
Also all video's actually contain two files an audio and a video. If you look in the file that holds the two of them you can sometime just listen to the audio.
You want to convert the mp4 format which you download from YouTube to mp3? Or just download the video from YouTube? Well, in both cases, there is an app which I use all the time and it's perfectly doing the job. I am using https://loader.to for both downloading and converting the videos which I need to mp3 format. Usually, these are remixes of the popular songs which you can't find on other platforms, and I save them to my phone playlist so I can listen to them whenever I want.
