The general idea behind that statement was, as I alluded to in another reply, was that they went through extensive effort to remove chance-based and savescum mechanics and systems from the game or to isolate and nullify their impact in anything but fringe cases-- Yet there still remained a lot of systems, some of them poorly implemented or unchanged, that still fell under that scope.
You had it right on the head with that last paragraph, the RNG aspects of the game have been wholly seperated from any sort of strategist or risk; the central gameplay elements are deterministic but are still flanked by random chance at every turn.
I may split that point into two seperate ones, or re-write it completely.
