Did you fill out the FASFA? If you did and your income is low enough, (below $50,000) you can qualify for Federal grants including Pell grants, but still these would not be enough to make a dent in the $62K/year costs for UCLA or any UC.
Amounts can change yearly. The maximum Federal Pell Grant award is $5,815 for the 2016–17 award year (July 1, 2016, to June 30, 2017). For the 2017–18 award year (July 1, 2017, to June 30, 2018), the maximum award will be $5,920. The amount you get, though, will depend on
your financial need,
your cost of attendance,
your status as a full-time or part-time student, and
your plans to attend school for a full academic year or less.
You may not receive Federal Pell Grant funds from more than one school at a time.

UC’s give mainly need-based aid to in-state students in the form of Federal grants/Cal grants and the Blue and Gold opportunity.
You can also take out a total of $27K/4 years in Federal student loans and if you are low income, you could qualify for work study. Again, definitely not enough to pay for a UC.
