My 16 year old did a couple of painting pottery things with friends as an elementary schooler, but didn't learn any techniques from it. Basically they served no artistic purpose. She learned a little in her public school art classes, which she didn't really like, to be honest, but they introduced her to various materials.
The REAL learning came from YouTube, like the PP's kid! She started drawing on her iPad during the pandemic, and has tried various softwares, free and paid. She draws and paints, and is now starting to work with clay. All from videos that artists post on YouTube to explain their techniques.
