From what I can understand:

A Jinchuriki has either an entire or some portion of a Tailed Beast sealed within themselves, with the ability to fully transform into that Tailed Beast. Obito only took chakra when he extracted Shukaku and Gyuki from Madara, not the actual beasts themselves.

A Pseudo-Jinchuriki has only chakra from the Tailed Beast, enough to manifest a chakra cloak, like The Gold and Silver Brothers, or Sora (if you take filler into consideration). So someone like Sasuke or Kakashi, who simply had chakra from a Tailed Beast wouldn't count.
