Hofburg and Sisi Museum Question

As I understand it both Hofburg and Kunsthistorisches Museum have a lot of divided sections with different tickets, but when I look at Vienna Pass aside from tickets for these sections there is also a House of Habsburg Tour ticket which refers to Hofburg.

I originally planned to buy the Sisi Museum and Royal Apartments ticket along with the Kunsthistorisches and Crown Jewels ticket which I gather is in the Hofburg, do I not get to see the main Hofburg with the Sisi ticket? Is the House of Habsburg Tour just a audio guide price or is it a separate area of Hofburg that I should visit to say I've seen Hofburg? As I understand it Sisi Museum and Royal Apartments is like 18 rooms.
