I think the visualizations are amazing for bringing concepts together, but you also absolutely have to do the work if you want to really understand and continue to work with the math concepts they talk about. I haven't really used 3b1b to advance my math understanding (I used it for math entertainment), but if I did, I would watch the video, work stuff out on paper, and then watch the video again
