Where do I find the Statistics module?
A quick search turned up this video from DrupalDude: Statistics module in Drupal 5

There's also the documentation for the module for the D5 version on Drupal.org that suggests you should be able to use statistics_get() to get the views for a certain node.

Something like the following would do it:

$stats = statistics_get($nid);

// Total view count
print $stats['totalcount'];
// Current day view count    
print $stats['daycount'];
// Timestamp of last view
print $stats['timestamp'];
