How do y'all unlock cap breakers every season?

I'll start by saying that I don't really play much, usually 1-2hrs per day, not everyday, mostly alone. When events are available I usually play a little bit more but not that much because it's still the weekend and I don't wanna spend it all raging at this game. With 2 weeks left in season 4 I started at starter 1 and I'm currently at starter 2 30%, I'm surely not making it to starter 3 and it pisses me off because I wasted time trying to get the cap breakers and I won't be able to, am I absolute garbage or is it really this much of a grind? I personally think of myself as an average player (maybe below average? Idk) as I shoot 49% from 3 and 61% fg playing alone, am I overrating myself? I haven't played the last few 2ks and this game feels so much different compared to the older ones, I think my last one was 2k20 and even that is extremely different, am I missing something? Am I trash? Do y'all get cap breakers every season? If you do, HOW? By playing a lot with friends? I really feel like either I suck, I'm missing something or the game sucks. Excuse me if I've made some spelling or phrasing mistakes, English is not my first language
