How to get top 10 user is based on user meta value

I guess you can do with get_users, something like:

$topusers = get_users( array (
    'meta_key'     => 'todayuserclicks',
    'meta_value'   => '',
    'meta_compare' => '!=',
    'orderby'      => 'meta_value',
    'order'        => 'DESC',
    'number'       => '10',
) );
