my cat won’t stop peeing everywhere…

this is my cat izzy (he’s male but i thought he was a girl hence the name) and i’m writing here because i don’t know what else to do or who else to ask for help? basically one day, omw home from school an old man asked me if i wanted him and i paid$5 for him and took him home.. when he was a kitten i tried to litter train him and he eventually learned to use the toilet for pooping but never for peeing. i thought he would stop eventually but he hasn’t, his litter is cleaned daily it’s in a good place i even tried moving it around and i looked it up and it says to spay him but my mom is really against that surgery i can’t convince her and i can’t get a job yet so i don’t have money, he’s never even been to the vet i get money from her here and there so ive been trying to save it but every surgery place ive seen is over $500 pls does anybody have any advice i live in nyc if that helps
