Copy the below from "theme.php" from the Sample Theme in the themes folder and paste into your "theme.php":
Copy:
// HTML template for the category list
$template_cat_list = <<<EOT
<!-- BEGIN header -->
<tr>
<td class="tableh1" width="80%" align="left"><b>{CATEGORY}</b></td>
<td class="tableh1" width="10%" align="center"><b>{ALBUMS}</b></td>
<td class="tableh1" width="10%" align="center"><b>{PICTURES}</b></td>
</tr>
<!-- END header -->
<!-- BEGIN catrow_noalb -->
<tr>
<td class="catrow_noalb" colspan="3"><table border="0"><tr><td align="left">{CAT_THUMB}</td><td align="left"><span class="catlink"><b>{CAT_TITLE}</b></span>{CAT_DESC}</td></tr></table></td>
</tr>
<!-- END catrow_noalb -->
<!-- BEGIN catrow -->
<tr>
<td class="catrow" align="left"><table border="0"><tr><td>{CAT_THUMB}</td><td><span class="catlink"><b>{CAT_TITLE}</b></span>{CAT_DESC}</td></tr></table></td>
<td class="catrow" align="center">{ALB_COUNT}</td>
<td class="catrow" align="center">{PIC_COUNT}</td>

<tr>
<td class="tableb" colspan="3">{CAT_ALBUMS}</td>

<!-- END catrow -->
<!-- BEGIN footer -->

<td colspan="3" class="tableh1" align="center"><span class="statlink"><b>{STATISTICS}</b></span></td>

<!-- END footer -->
<!-- BEGIN spacer -->

<!-- END spacer -->
EOT;
Paste into your theme.php and edit out the <span class="statlink"><b>{STATISTICS}</b></span>
or even edit it to have what you want it to say or to take out the row. The below removes the words but leaves the row.
// HTML template for the category list
$template_cat_list = <<<EOT
<!-- BEGIN header -->
<tr>
<td class="tableh1" width="80%" align="left"><b>{CATEGORY}</b></td>
<td class="tableh1" width="10%" align="center"><b>{ALBUMS}</b></td>
<td class="tableh1" width="10%" align="center"><b>{PICTURES}</b></td>
</tr>
<!-- END header -->
<!-- BEGIN catrow_noalb -->
<tr>
<td class="catrow_noalb" colspan="3"><table border="0"><tr><td align="left">{CAT_THUMB}</td><td align="left"><span class="catlink"><b>{CAT_TITLE}</b></span>{CAT_DESC}</td></tr></table></td>
</tr>
<!-- END catrow_noalb -->
<!-- BEGIN catrow -->
<tr>
<td class="catrow" align="left"><table border="0"><tr><td>{CAT_THUMB}</td><td><span class="catlink"><b>{CAT_TITLE}</b></span>{CAT_DESC}</td></tr></table></td>
<td class="catrow" align="center">{ALB_COUNT}</td>
<td class="catrow" align="center">{PIC_COUNT}</td>
</tr>
<tr>
<td class="tableb" colspan="3">{CAT_ALBUMS}</td>
</tr>
<!-- END catrow -->
<!-- BEGIN footer -->
<tr>
<td colspan="3" class="tableh1" align="center"></td>
</tr>
<!-- END footer -->
<!-- BEGIN spacer -->
<img src="images/spacer.gif" width="1" height="7" border="" alt="" /><br />
<!-- END spacer -->
EOT;
