Would I realistically be accepted into a grad program after 10 years in the service industry?

I graduated from NYU IN 2017 with a BS in Media, Culture, Communications. I worked as an assistant to the owner of an art gallery for two years after graduation, but then transitioned to the service industry and have worked in it ever since. I really can’t handle the service industry life and I am extremely interested in going back to school to study PR, communications, or marketing.

I feel pretty bleak about my options right now. Would a grad school even consider an applicant like me, with no academic or industry related references? I have considered taking the GRE to strengthen my application and I would have to write a fresh writing sample as everything from my undergrad is so dated.

Please be honest with me.
