From something called the California Progress Report:

"While the statewide vote will provide a candidate with “momentum” and a victory, what is lost with this focus is that we are electing delegates to the Democratic National Convention—and that the bulk of the action here takes place locally, in each of our state’s 53 Congressional Districts. 241 of California’s 441 delegates are elected based on the share of the vote the candidates for President receive in those districts. Only 81 delegates are elected “at-large” and go to the winner of the statewide vote.

"The remaining 119 delegates are selected (not elected). These include 66 “super delegates” (Members of Congress, Democratic National Committee (DNC) Members, and a former DNC Chair). Also 48 Pledged Party Leaders / Elected Officials (PLEOs) committed to candidates who receive at least 15% of the statewide vote and apportioned by their share of the vote. Another 5 are also appointed who are “unpledged” to any candidate."

Billary gets the 81 winner's share and her portion of the 241 based on % vote. The 66 super delegates will go to the highest bidder and god knows how the other 53 work.
