A profession requires many years of study, such as being a doctor. Professions also require special training. An occupation is a type of job, such as being a farmer. If someone works as a farmer but studied medicine and is a doctor, their profession would be a doctor but their occupation is a farmer. Being a lawyer is considered a profession since it requires many years of study and training. Graduating from many years of study means you would have a profession rather than just an occupation. Getting a job without needing to study would be considered an occupation rather than a profession.
