If i rented a house(guarantor paid for), attended college, and worked in CA during 2024, am i considered a resident? does the renters credit section apply to me or no?

If you rented in California for more than half of the year and did not live with anyone who claimed you as a dependent a (and meet the other qualifications) you can claim the credit as a nonresident.  See Nonrefundable renter's credit - Franchise Tax Board - CA.gov
