it is possible to get married whilst you are in med school and its happened before. also, if you get into medicine in your first try and you do not have to retake any years then you will graduate at 23, do your F1 and earn about 23-25k (but it varies from palcement to placement) but this wage will continue to increase over the years (some consultants earn over 150-200k, but it takes a really long time to become a consultant), so effectively you have a job at 23 which isn't that bad, but true, the working hours are HORRIBLE.
