in need of reality check?

I went to a very good scottish uni but got no work experience whatsoever (just worked as a waitress during the summers, did some society committee stuff and some online work experience). I'm kinda old compared to most people looking for grad jobs (24 because I took a year off before uni to save money, did a four year history degree and have struggled to find  graduate job since graduating in 2022) so I feel like I should give up and start looking elsewhere

I've worked in receptions/admin since and did a week of shadowing at a big4 firm, in the meantime i've been developing my knowledge by reading and doing courses online through sites like this but i don't have many opportunities for networking since I'm the first in my family to graduate, although I guess I could walk around on my lunch break to chat with people). I guess my one saving grace is I live in London and I've now saved up enough that I could do an unpaid internship for a considerable amount of time (but not enough to do a masters). Anyway, I'm not really sure what to do to improve my chance aside from focusing on something else for the timebeing and then doing an MBA later
