My amateur thoughts:
In fast chess (bullet, blitz, rapid), where having little time everything is based on short calculation, on the recognition of patterns accumulated in memory and on intuition, probably yes.
In standard time control games that last hours, and when you're at advanced levels, I imagine it's very different. I don't believe you can face the middlegame without preparing long-term plans (strategy) based on deep analysis of the position, or that you can identify the strategic maneuvres needed to win a complex endgame simply by calculating sequences of moves.
I'll let the experts who know much more than me speak, but I guess that the meaning of that famous phrase ( by Teichman ? ) is not the brutally literal one. Masters, enlighten us.
I'm of the opinion that Chess is really 99% all tactics.
Without a solid grasp of tactics, one can't really grasp the rest of the game.
