how the hell do dns server requests work?

A DNS server is like a phone book. It stores IPs the same way a phone book stores phone numbers. Sometimes a name or a record can have more than one IP. Much like a business can have different phone numbers for different departments your DNS records could have different information based on your request. For example the MX record tells people where to send email.
Your computer sends electrical signals to port 53 to make a dns request. Think of a port like a door. Door number 53. Every computer and server on the internet sends data to and from doors. Some have doors open waiting for people to connect to them. As is the case with dns servers. The doors are numbered 1 to 65535. The same services often wait for connections in the same doors. So dns servers across the planet typically use 53.
