What does gallery stats mean like Thumb?

[jinspin]

I would like to make sense of this. What does the gallery stats mean?
For example -

<table><tbody><tr><td align="right">Thumb: </td><td align="left">8 </td> </tr> <tr> <td align="right">Small: </td><td align="left">1 </td> </tr> <tr> <td align="right">Medium: </td><td align="left">3 </td> </tr> <tr> <td align="right">Large: </td><td align="left">11</td></tr></tbody></table>
So does Thumb mean when user clicks on thumbnail in gallery?
What is small?
And does Large correspond to XL XXL and Original sizes?

When does the stats get updated? I tried clicking on different sizes and they didn't seem to update right away.
