My problem with the advice for forwarding ports for games like Valorant, is that often they are wrong. To understand whether port forwarding is needed you need to consider the way the game works.
Some games connect to a central server using UDP and/or TCP, and all communications occur using the channels that are already open.
If this is the model that valorant uses then there is no need to set up port forwardig anyway.
Other games work on a peer 2 peer connection where one game instance connects directl to another. (An example of this is Splinter Cell: Blacklist)
In that case you do need to set up port forwarding (unless the game does it using UPnP).
Reading up on Valorant, it looks as if they are using the first type of setup as they discusss having servers in different regions - EU/Japan/North America and not allowing gamers in one region to join servers in a different region. So port forwardig is not going to help.
