Title IX doesn't require the same opportunities. Rather, it prohibits school sponsored discrimination. In most HS and Colleges, one sport rules ... Football. The second sports behind football is football. The third is probably basketball. Then soccer, water polo, cross-country, etc. Title IX simply requires schools to provide an equal number of athletic opportunities (or at least that is how its been interpreted). Because football is so popular and basically a boys sport, schools tend to promote other girls sports to balance out the fact that their dollars are going to football. This means that the other boys sports have less support and tend to get killed. In high schools you will find girls volleyball, but no boys volleyball teams because ... football and Title IX.
There is a perceived inequity between football and other sports. This is not because of school sponsored discrimination, rather, football is actually a profit center, whereas most other sports are not (basketball often an exception). Football is the one sport that has programs with advertisers, boosters that raise tens of thousand of dollars, and stands filled with hundreds of students and parents (in some cases thousands). The same argument exists between the Men's and Woman's US Soccer teams. Men are paid more because the men generate more money in advertiser and ticket sales.
With regard to the CIF, they actually have initiatives directed at informing the member schools and parents of the various equality programs:
