For UCs …
For 2019, applicants with weighted-capped GPA >= 4.20 had admission rates of 38% to UCB and 35% to UCLA.
If you are applying to L&S, then these should be reasonable chance estimates (of course, essays, extracurriculars, etc. matter, but outsiders like people here cannot tell you how your essays compare with others in the applicant pools). The engineering divisions should be considered to be more difficult to get admitted to.
