To understand the profound racial prejudice in UC Davis admissions consider that of the applicants 12% (520/4230) were Black/Hispanic yet 27% (55/204) of the acceptances went to Black/Hispanics.
One would expect something like about 24 (204 times .12) to have been Black/Hispanic yet there were 55 accepted. Could this happen without racial bias? No,this is mathematically impossible. In fact, the chances of this many Black/Hispanics being accepted is much less than 1 in 100 million even if all of the applicants were academically equally qualified, which, as the scatterplot below shows, they are not.
