Please chance me for Californian Universities as an average student [TX resident, 3.16 UW, 1220 SAT, low income]

Yes. It looks like out of state pays something like an additional $444/unit. So at 24 units, annually, the minimum full time number of units, that’s an additional $10,656. Tuition is currently $6450/annually. That comes out to be $17,106 annual tuition before room and board for out of state.
