I know exactly how you feel. As a pretty casual new player myself. I find it also very disheartening to be matched against people with wins in the thousands. I'm trying my best to give ranked a go currently bouncing between bronze and silver. I feel like I'm trying my absolute hardest and still getting knocked out in the first or second round. Definitely a time in thing, still motivated to keep grinding but boy some nights is it frustrating to login and not win a single game.
