besides GPA, the other critical thing to have on your resume is Research, and the question is whether you have the ability to enter into meaningful research at CalState. (UCLA undoubtedly has more opportunities, but also a lot more folks gunning for those slots.)
You won’t be, but recognize that the student from UCLA with A’s in the major will almost always score an interview before you will (other things being equal).
But agree with the others…no need to extend a year of expense just to transfer. Instead, use that year to gain more research experience.
