do you want to learn flamenco techniques? there are a zillion youtube tutorials on rasgueados, on alzapua, on picado, etc.
i find that you can watch the legends and masters directly playing their music, and watch their fingers.
song forms, chords, all can be learned if you know what it is you seek to learn.
i taught myself flamenco guitar to quite a high level of competency during the pandemic, and i can promise you that with a few hours practice a day, and some passion for listening to and discovery of new music, you too can achieve what normal mortals consider to be extremely developed skills, because, truth be told, it's like any human endeavor: you can get competent quickly, but it will take a lifetime to master.
playing a musical instrument is a different modality than verbal wankage and supposition about this or that, aka it's the opposite of an online comment, IMO
