Yes, this is true but not what those vids are about. I watched through most of 7 of the 9 and he is speaking not of Jewish traditions that come from our people and the Torah, but instead going back to Nimrod and the religion that has been passed down and the things that are done today in the name of Jesus that had nothing to do with him. I was aware of 99% of the stuff he presented but there were a few surprises.
The seed of Satan has been with us a long, long time, so far back that today it is called myths, but that's what he wants you to think so you just pass it off.
These 'traditions' that he is speaking of are nothing but evil and emanate from the evil one himself who wishes to depose G-d, and he had a long and convoluted, tangled, and intertwined history in which he has been laying this framework out, so big it has been missed for years. But now in the end when information is available for those who seek the truth of G-d, it can be seen, and the warning he gave us can be heard.
