I think that, yes, the success depends on a degree.
Of course, there are different situations, different people, degrees and so on, but in my opinion, having a degree is beneficial for the future. University is a place where you meet new people, create connections, learn a lot and improve skills. I've never regretted my choice to become a student. Yes, it's hard, but nowadays, there are a lot of useful resources and helpful sites. I use a lot of such sites, and https://edubirdie.com/ is my huge helper when it comes to writing tasks. They can be too hard to finish, and such help is beneficial. But I work on my skills, and the university provides everything for it.
