Getting a finance-related entry-level job in the UK after brexit with no experience : am I screwed?! [salary threshold]

Hello everyone.

I am from Europe and I hate my country. I was hoping to get a job in the UK. I am concerned about the Brexit immigration points system. I will soon hold a master's degree in a quantitative STEM field which is heavily loaded in math. I do not wish to pursue a PhD or an academic career. I am somewhat old due to life circumstances (currently 25, I'll be 26 when graduating) and have no experience. I have not applied to any jobs right now since I am still a student, but I will do so whenever I get my degree. However, I am worried due to the salary threshold. Indeed, I know that to immigrate I need the 50 mandatory points, which shouldn't be too hard to get if I get an actual offer if I understood correctly, but I need to fill out the last 20 points. To do so, I would need to be paid the "going rate". I assume this is the average salary of everybody in the profession, and does not take into account the fact that I have no experience, right?. Will this bound me away from an entry-level job? I know an alternative way would be to get experience elsewhere and apply later to hope for a larger salary, but my country is truly miserable and I want to flee as soon as possible. I would have taken on a job with a much lower salary than "deserved" if I could immigrate, but this system prevents this (I guess it is the point, the UK wants to protect their citizens, this makes total sense to me and I am not criticizing this choice).

Another way to get the 20 points would be working a job in which there's a shortage of applicants, which would allow me to lower the salary threshold by a factor of 0.8. I took a quick look at a list of those jobs and it seems like engineering and programming are in demand. Would landing an entry-level job in, say, programming, allow me to break into the financial sector later in hope of attaining the minimum threshold? Even then, I have a feeling that landing a programming job at 80% of the rate won't be easy since I don't code regularly (but I can train quickly in python and C).

It seems like I'm screwed and this is truly depressing for me, as I can only speak English (aside from my native tongue which is useless anywhere other than my country which I want to flee desperately) and do not hold a green card, which means working in the US is almost impossible too (this would have been my second choice after the UK). The other immigration possibilities in an English-speaking environment seem scarce. Am I going to make it? I want to hang myself.
