What are defined as "Errors" in workers

Ok, I noticed how when viewing workers requests are broken down into “Success”, “Errors” and “Subrequests” I know what success and subrequests are (and believe I know what response codes are defined as errors, which are listed below)

The following response codes are defined as errors (I think)

  • Error 500: Internal server error
  • Error 1027: This website has been temporarily rate-limited (exceeded daily worker requests)
  • Error 1101: Script threw exception
  • Error 1102: Worker CPU time limit exceeded

Am I correct on that? Do the response codes above count as an “Error”?
