This is correct, most of those scripts can only delete 1000 comments from new/top/controversial.

The method to delete all your comments is as follows:

1. Do a GDPR request for a copy of your data using: https://www.reddit.com/settings/data-request. Wait until you get the zip file, then extract it somewhere.
2. Download the free utility shreddit from https://github.com/andrewbanchich/shreddit and point it to the directory where you extracted your GDPR data using the --gdpr-export-dir flag.
