Yersl; Can you please show me where in Chumash (OK, Chimish) it says you should only drink Cholov Yisroel?! You (probably a Bais Yaakov Grad) may, or may not have learned Talmud. The source of this Halacha is in the Gemara. Namely. That if a Jewish person did not observe (was not present) the milking process, it is called “Chlov Akkum”. But you’re right on the point. There is no such thing as Cholov Stam. It’s either Ch.Y. or Ch. Akkum.
