I think there's some confusion between a professional role and a progressional job.
A profession is a job would require a degree- doctor, dentist, surveyor, teacher, lawyer, architect, engineer. All jobs you could not do without training at degree level.
A professional role would include jobs that don't require a degree, but there are often qualifications that can be taken specifically for the role, such as estate agent, teaching assistant. financial advisor.
And then there are jobs which require training to do, but not a degree, such as hairdresser, plumber, electrician. They are not professions, they are trades.
And then there are artists, actors, dancers. All things you can take a degree in, but they're not professions, although you can be a professional artist, professional actor, professional musician etc.
