User ID received in Data Deletion CSV and relation with Graph API ID

Hi, I'm seeking clarification regarding the User ID received through the Data Deletion CSV present in admin dashboard and its relationship with the Graph API ID field.
We receive user data through the Graph API during authentication using the 'id' field (fields=id,name,email)
Can someone confirm if the user_id in the user ids CSVs exactly matches the 'id' field we receive through the Graph API (fields=id)? We need to ensure we're correctly identifying and deleting the right user data when processing deletion requests.
Thank you for your assistance.
