i think nowadays PhD or some degrees like this does not that works. you can get professional from a lot of different ways. such as using MOOCs. internet has changed everything.
There's a huge difference between having a Ph.D. or any degree but it's also true that someone can be a professional without having that.
But it's all up on your career plan and path if you are requiring for that and what you'll be taking in school to pursue as your career.
