Agree with this. There is no shame in making an honest living from financial consultant or housing agent sales. OP can then save up for studies or at least have side income while pursuing higher qualifications. These are essentially self-employed jobs, so depending on your team targets maybe can work out a schedule that can fit in studies.

This way, OP will also be a happier person by not being saddled with “student” debt or borrowing from relatives.

No offence but I also think OP is too picky. Even graduates can have difficulty getting recruited in competitive industry. Is it better to earn an honest living and gain some experience in people skills (which can also help if you move to your dream companies) or remain unemployed jumping between part time work. Your choice.
