I mean, blackjack is about luck but a little bit of skill too and i was wondering if someone made the definitve strategy for online blackjack like if you get 12 then you have to stop or get another card, etc
There are no rules, there are no definitives, there are no guarantees. That's why it's called gambling. If there was a way to always win, don't you think everyone would always win all the time? Not how real life works.
