Congrats. You would have known before now if there was issues. They will send a "procedural fairness" letter, giving you the last chance to correct your file.
You will get your DM letter (eventually). You will also get an invitation letter to a landing interview. This is like getting a driver's license. Answer some very simple (not trick) questions, review and sign the COPR there, and you're done. Off to get your permanent SIN and update your provincial/territorial health insurance. And, of course, party!
No need to be nervous at all. Excited is better
