Is becoming a paramedic competitive

Context - Im in grade 11 and my marks aren’t all that great so far (100 in accounting, 94 in uni chem, 94 in comm tech and 67 in uni English) Sadly those marks aren’t competitive enough for nursing and truthfully paramedic sounds so much more fun then nursing. I just wanted to know how competitive it is. I know becoming a police officer or fire fighter is hard and people often have to build their resume for a couple of years before they even get a shot. Will I get hired straight out of college. How much do you make?
