I would look up the difference between witness data and core data in a tx. Segwit let's you put more witness data which leads to the increased block size, my mind isn't liking the phrase "create space" because it sounds like it became more efficient/took up less space but that's not the case. You use extra storage for every block on your bitcoin node since segwit was introduced.
