Some of those statements are ... forward-looking. In particular, Dragon isn't man-rated yet, and that will require a lot of further engineering. Most notably, SpaceX has committed to a launch abort system for getting a crewed Dragon away from a failing booster; they've got a concept for this, and design work is underway, but it's not tested as of now, and I think some of the work is probably contingent on getting NASA funding to finish up. So, Dragon can't carry astronauts yet.
