With QQ we should be good against the majority, but the tightest people. While some players play tighter (they don’t play many hands) than others a good rule of thumb is pocket kings and aces are always strong enough to get all the money in the middle preflop.
For now, know when the opponent goes all-in preflop, he will have a decent hand unless they are aggressive players willing to bluff their stack. I will go deeper into the strategy in another article as it is a massive topic on its own.
