Question on minimum age for rental cars in USA

I am going to San Francisco on study trip around April. We have the possibility to stay longer in the USA. We only need to get to Los Angeles. So we looked for a rental car because we would like to do this trip. I have looked at Avis and Hertz. I looked at Avis on this website: https://www.avis.be/ I am 20 years old. The cheapest car I could find is Chrysler Town & Country for €239.35 for 5 days. Then later I looked at this website of Avis: https://www.avis.com/en/reservation/make-reservation I get an error

Based on your age selection, there are no cars available at this location

So my question is why do I get that error? Is possible for 2 guys with the age of 20 years to rent a car in USA and do that trip?
