A profession is a job at which someone works and for which they have had training. It is what they do to get money or a living. People often study for years to do their job. Examples of a profession would be a teacher or a lawyer. These are called "learned professions". Sometimes "profession" only means learned professions, but sometimes the word may also be used for other jobs. Someone who works in a profession is called a professional. Sometimes this is in contrast to amateur which means someone who does similar things but is not paid.
