Custom Labels are stored as metadata, and so they are not accessible when you perform an export, import, or delete using Data Loader.
While there is no native functionality to export Custom Labels into a CSV, there's a workaround you can use to create a spreadsheet containing your Custom Label information.
To view alternate solutions with the Apex API, visit the Idea Exchange link to Access Labels in Apex Dynamically.
