It could be that they define logistics sector very broadly intentionally so that it includes a high number of low pay workers, such as those making minimum wage. Or, how Amazon defines the aggregate of "salaries paid to its workers" — average, median, max, etc? I'm generally skeptical of hand wavy claims that like this that shy far away from real numbers.
