Not necessarily. There were two "types" of monks: choir and lay monks. The choir monks were usually priests (male monastic communities select which of them become priests) and would spend most of their time in the choir, literally singing the prayers of the community (big deal in monastic setting). These were usually the wealthier people and they were often physically separate from the lay members, who were not taught Latin (and thus couldn't sing in the choir) and were responsible for the physical upkeep and labor of the monastery. These usually went to members who did not have any familial status or wealth. So people could join, they just were often tasked with the manual labor and less glamorous jobs.
