how common is it to not play ranked?

hiii im pretty new to the game (level 35 and have been playing for maybe a month?) and ive mostly played aram and have found it rlly fun!! im only now just venturing into the community outside of a few friends who play somewhat in infrequently. ive noticed that rank seems to be rllyyyy important to ppl so i just figured id ask this and see if its weird for me to just be hanging out in aram lol.

i would try for real SR but i was so put off by the singular quickplay game i played that lasted over an hour and ended in horrible defeat. i just. dont have that kinda time or attention span sadly

would love any sort of advice/thoughts! im in uni and have a job so i dont have the most free time but i would like to improve!
