I think you are getting quite the wrong idea... I mean sure you can, but it will be stressful as hell to make your literal first game on a jam, you shouldnt even make a full game first, as you will probably go over the scope and have a hard time implemeting your ideas, you should learn slowly by making prototypes and actually learning to use your engine of choice and its lenguage if you want to program, however its completely up to you, just dont give up on it if it seems too hard
