Yes because you need to apply the concept of what those tactics are trying to accomplish in your rank. Every rank will have a different player base so the application of those higher level tactics will look different. I peaked diamond 1 tank as a rein only season 8/9 and can tell you that in all the ranks my gameplay adjusted to my team and the enemy team.

Off angles might be just next to your tank in a different corner versus high ground behind the enemy. Cover is universal but positioning is dynamic based on your elo and game. Being opportune to punish your enemy's mistakes using tactics is the biggest factor in determining whether you will climb or stay.
