Trying to push my horse into position so that I can fork my opponent's king and rook then capture the rook.
Is that a tactic?
Yes because a "fork" is a common tactical theme. A "tactic" is a sequence of moves which aim to gain an advantage of some sort. The definition of a tactic would be something like that.

Is that a tactic?
Yep, that's one of the most common tactics in chess
"Tactics" is moves or sequences of moves that result in a clear short-term gain, usually of material or checkmate.
"Strategy" is moves that involve a plan for long-term benefit, such as better pawn structure, a favorable endgame, or making an opponent's king more vulnerable to attack.
The example you give falls into the "tactics" category.
