Tere Tere Erki!
To answer your question, whether 'professional or non-professional jobs are better' depends upon your point of view. People will always have their own opinions. We all place value judgments on different kinds of success based on our own priorities. You benenfit from deciding on your own views.
For example, if you're a talented football player and your idea of success is making a large salary, having a non-professional job on a sports team, even for a few years, would make you feel successful.
Then again, if scientific learning is your goal, like the sister of a friend of mine, you might complete a professional medical degree and then fight for $35,000 grants each year to perform cancer research to feel successful.
Of course, if earning money isn't your idea of success, yet developing intellectual learning is, you might earn a philosophy or cultural degree and then work for someone like the Dalai Lama. Estimable may not be your goal.
Its useful to point out that traditional professional services are changing dramatically as the result of globalisation. People may train in one place and move to another to practice. Professional standards are increasingly internationalized in many sectors yet, sometimes recertification is still required in different countries. If you find your passion, you're more likely to make sacrifices to alter your own idea of success. Consider my Estonian grandfather. He was a physician in Estonia, fled during WWII, recertified to practice in Germany, moved to Italy, recertified in Australia and then in Canada.
