Unintelligible Gemara

Is the Gemara known where the demi of an apocrypha is? “He who says, “May the Lord and his rabbis teach us, and may our rabbis teach us” I do not understand two things: a. How is Torah different from all other wisdom? Even Greek wisdom is useful in this wisdom. What is the added value of Torah from all other wisdom? b. Let us assume that we understand what is the added value of the wisdom of the Torah beyond other wisdoms. Why is this the reason why a person has been reduced to the serious status of an apocrypha? They will say that he made a big mistake, and so on. What is the connection with apocrypha?
