Hello Abby,
Thanks for reaching out with your question!
Unfortunately at the moment it is not possible to export only attendees of a certain ticket type / ticket name.
If you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there.
Once you export the whole list, and open it with a spreadsheet software, it should be quite easy to filter your list the way you want it.
If you copy the exported table to Google Sheets, then select the whole table, including the top row with the headers. Click on the little funnel icon (marked with red on the below screenshot). That will switch on the filtering option. Afterwards you can filter your list by clicking on the little down arrow in the Ticket Type cell.

Let me know if this helps or if you have any other questions.
Cheers,
Andras
