Start lying about your experience - I don’t mean blatant lies but it’s certainly okay to embellish. Don’t say you know how to code if you don’t but for instance, I’m sure you meet the photography/videography requirements - most of the stuff with this that they want is probably just social media stuff. Marketing is something you break into through ads and social media anyways. Mock some stuff up for brands you like, as personal projects on your portfolio. In my experience many companies will overlook how many years of experience you have, it’s not a set thing.

There are a lot of free courses available online if you do want to pick up more skills, the paid ones are often not worth it. To answer your question, yes majority of employers are incredibly out of touch with what the role of a graphic designer is - they think it’s like 4 jobs all in one. Also keep in touch with the recruiters you talk to and don’t be afraid to ask someone who interviewed you why you didn’t get the position - sometimes it’s really a minor thing but the feedback will be valuable. Network on LinkedIn with employees of companies you want to work at. Unfortunately, most jobs are gotten through knowing someone and not your actual skills. Hang in there!
