Is GitHub Action only for GitHub Workflows?

Excuse me,
Can you say me if Others and I can use a GitHub Actions only into GitHub Workflows.

Thanks,

GitHub Actions execute workflows on GitHub Runners in response to events. An action can interact with services outside GitHub as well to enhance the E2E workflow.
