Do I leave my current job without any backup ?

I am working here since a year and the pay is low the timings r like 9:30 to 6:30 for 6 days a week and I learnt 0 skills and I do repetitive manual operations work in the name of associate product manager.

Im 20 and I am gonna graduate this month , but im planning on doing a 4th year , but still unsure , also I dont rely on my salary for living its just extra cash for me I dont need it per say.

No skills , repetitive boring tasks, and also I speak to 0 people in office literally speak to no one. I was close to my boss but we fell off so now its js silence. And the job timings and the pay and all is js ugh

So do I quit this job without any other plans , im not getting any job offers as of now , lol idk, if I keep waiting to get a job imma just be stuck here for long .
