[Art Galleries] Could I get a job at a gallery with my weird mix of job/education experience?

Apologies in advance, I was grocery shopping when this idea formed and im typing this post in the parking lot. I was going to school for art education, but pivoted to just get my general AA after getting a job that pays what I would get as a teacher, but with no degree requirement. The US not making up their mind on the department of education's existence and me being trans doesn't help. Now I work in billing for a Healthcare agency and honestly its sucking the life out of me. Its super easy but shagging old people for money doesn't feel the best. I had an idea. Galleries sell art, so there has to be someone who manages that transaction, right? Art was always my best subject but math is a close second, I can manage a spreadsheet and make and send invoices and process transactions with large dollar amounts no sweat. Im sure that many gallery owners would like a more business and numbers minded person on their team, with the bonus of me having a background in art. I could be insane for making this connection, I just got off work and had 4 hours of sleep last night but I had to ask. I know I couldn't go for a curator role, but do financial assistance positions exist?
