AFAIK Thunar gets them from the MimeType= line of  the .desktop files
spread on your system (e.g.  /usr/share/applications/gimp.desktop).  I
don't know of any priority for this, so the result may be random. 

If the default doesn't fit, you can right-click on a file in Thunar and
select "Open with other application".  A window will be opened where
you can select your preferred application and select "Use as default
for this kind of file". This information is saved in
