If you accept a spot on the waitlist, you might get in. From what people have been saying on the UCSC decision thread, many have gotten off the WL in years past.
Many students don’t learn how to manage academics until they are in college. You have great options already, so I think you’ll do well.
Update: Got rejected to cal poly slo today.
