Even so; just because (something) is true, that doesn't necessarily mean (something else). Used to qualify a previous statement.
彼は有名な教授だ。だからといって何でも正しいわけではない。
He is a famous professor. That doesn't mean everything he says is correct.
忙しいからといって食事を抜いてはいけない。
Even if you're busy, that doesn't mean you should skip meals.
高い＝良いとは限らない。だからといって安物を買えばいいというわけでもない。
Expensive doesn't necessarily mean good. Even so, it doesn't mean you should buy something cheap either.
経験があるからといって、すべての場面でうまくいくとは限らない。だからといって挑戦を避ける理由にはならない。
Having experience doesn't guarantee success in every situation. That said, it's not a reason to avoid trying.
