I hear you Bro. This happens to me the same way when I read some community content, sometimes I get a little frustrated because of that, not knowing or knowing more about the game being talked about.
But for what it's worth I can tell you that TFT is something like magic chess. You place your champions and start putting together a board with the best synergy you see fit.
If you dare to try it you can tell me, I will help you without problems 😁
