How much elo do I have to be to become a good player?
If you want an objective answer then you'll need to be more specific than "good". Chess.com will show you the percentile which your ability level is in. You're in the top 50% of active players. I'd say that's pretty good. 1500 would place you in the top 3% of active players. I'd call that exceptional.
I know this question has probably been asked about a million times, but I want like an objective stance at this. I'd guess around 1500 elo?
