Most CA schools do have an AVG of 20's so that does mean they accept students that have scores below a 20. I think your PAT score is decent since I also got a 17 but I think thats pretty low when looking at CA schools. It sounds like you might be a CA resident so that may improve your chances. You will get in somewhere but I hope you get in to the school of your choice and nice job on the DAT 🙂
