Is regret and mistake the same thing?

Regret and mistake are related but not the same. A mistake refers to an error or an action that leads to an unintended outcome, while regret is an emotional response to recognizing a mistake or a missed opportunity. You can make a mistake without feeling regret if you learn from it or view it as a valuable experience. Conversely, you can feel regret about a decision even if it wasn't technically a mistake, especially if it contradicts your values or expectations.
