Well, there's always 3Blue1Brown: https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw Take a look at his course, Essence of Calculus: https://www.youtube.com/watch?v=WUvTyaaNkzM&list=PLZHQObOWTQ... I'm not fluent in math, but I find it fascinating to watch, for some reason. NancyPi is also great: https://www.youtube.com/channel/UCRGXV1QlxZ8aucmE45tRx8w Oh, and don't forget the Mathologer: https://www.youtube.com/channel/UC1_uAIS3r8Vu6JjXWvastJg What a great guy! While I'm at it, go watch Numberphile too: https://www.youtube.com/user/numberphile Is there anyone I forgot? :D
