I don’t understand how a network card or even the software on a network card can make a virtual port and then make sure that traffic is processed alongside every other port. What are these ports actually and how do they work. literally not the same repeated stuff I find on every website when I search “what is a port” i’m looking for a much more in depth understanding.

Wow, no-one explaining like he’s five… It’s all very correct but still too complicated for a five-year-old.
Think of a computer as an appartment building and the network card is the front door. Data comes through the front door like packages. The appartment building address is the IP address and the appartment number is the port number.
The package has a destination: address and appartment number (= IP address and port number). It also has a return address written on it in the same format, that’s how replies are sent.
Obviously there’s more going on (read the other answers) but this is the gist of it.
