Thank you for reaching out.
As per the documentation, For Search people, the requests allow you to search for people relevant to the signed-in user (/me) and other users in the signed-in user’s organization. These requests require the People.Read permission, with the exception of searching other users’ relevant people, which requires People.Read.All. By default, each response returns 10 records, but you can change this by using the $top parameter.
Hope this clarifies the doubt. Do reach out if you notice any more discrepancy.
Thanks.
