Hi, and thank you for asking your question.
Delivery Status (Failure) emails are automatically sent by your email provider when an email is sent out to a wrong/non-working email address; it looks like your account might have been compromised and spam emails are being sent out in bulk on your behalf (but without your knowledge), leading to these received delivery status emails.
May I connect with you remotely to troubleshoot and secure your Gmail account now?
Please reply back to me below. Thank you.
