That is not true based on what I read in the section of the Talmud on it’s history. It includes all of the traditions of the Pharisees, not just their oral teachings so following it to the letter would be doing as they did as well as doing what they taught.
Well I don’t know then. Just remember as you read through it that a tradition is only bad if it contradicts (or nullifies) the word of God.
So if a tradition says to wash your hands before you eat, well that’s fine. On the other hand, if a tradition says to give your money that was intended for your parents as a Korban, that’s bad.
