てことは is a more informal version of ということは, which means "That is to say ..." or "What this means is ...". 梃子【てこ】 ("lever") is not relevant as all.

て (or って in the middle of a sentence) is a colloquial particle that works like という. て/という refers to what has been mentioned in the previous context. You may have seen sentences that start with という, like in というのは, というわけで, と聞きました, etc.

えっ？　てことは、君はまだ学生なのか？
Wait, does that mean you're still a student?
