How often do you guys have absolute bad rounds in ground top tier?

I’m new to top tier and get nearly every round completely destroyed. Rounds with 0 kills and back to the hangar in the beginning of the round. I have very rarely good rounds, like one round I had with 7 kills. Especially asking the very good and experienced players. Do you have those rounds too? So it’s just how top tier is, or do I have just a big skill issue? So is it normal in top tier to have very bad rounds most of the time?
