Through the years i’ve seem a lot of games with high latency that tell me to do it. I just never did it nor know how or what it does.

Imagine all the different devices that are using your Wifi as apartment buildings with each program living in one apartment. Now imagine your router as a gatekeeper controlling access to and from your device neighbourhood.
Ports are like the postboxes of each building, so that if you want to talk to f.i Quake you need to put your letter in to the port reserved by Quake in the computer running the game.
However, how do you get past the angry looking guard that is the router? He will happily take your letter and bin it, because he does not know who this “quake” person is and he is not going to find out what apartment has his postbox.
Port forwarding is like you going to the router and saying “I like to reserve one of your community P.O boxes. Whenever someone comes with a letter and puts it in this P.O box, please take it to my Desktop apartment and put it in postbox 140, where Quake lives.
This makes the router happy. Now people can send letter to Quake, leave them with the router, who sends it on to the correct device and program, instead of angrily chucking it in the bin because he doesn’t know where it should go and if it is safe or not.
