you've never uploaded anything to YouTube i can tell, if you don't select a thumbnail it automatically takes a random frame from the video

if you don't select one it doesn't upload with a blank thumbnail lol

Why are you assuming that one of the most followed people on the YouTube platform is not reviewing his own thumbnails? Dude could have a social media team entirely responsible for his posting schedule. It *could* be a random snapshot from the video, but that's not the most likely explanation.
