No! The "failed to bind" error occurs whenever a program fails to take control of a specific network port. In this instance, Nginx is having a conflict on either ports 80 or 443 with an existing service in your machine. You can identify which program is taking up this resource by running this command: netstat -tulpn | grep -e :80 -e :443.
Once you know which program is causing the error, run apt remove or systemctl disable to stop the program.
For example, Apache is a common program that takes the same ports as Nginx. You can disable this in Debian by running the following command: sudo systemctl disable apache2.
