Is it difficult to find a job in the field of marketing?

I know I’ve been asking a lot of questions about careers and education lately. I’m just trying to find out as much as I can about it. Anyways, I want to study business but I’m thinking of studying specifically marketing. I read online that it’s tough to get a job and very competitive. Even if I can’t find a job in marketing, will this degree give me the opportunity to have a good job even if it’s unrelated to the field?
