Super basic question on linking domain to server

I have a super basic question. I have a GoDaddy account set up with subdomain xxx.mydomain.com. I also have some services running in an AWS instance on xxx.xxx.xxx.xxx:7000. My question is, what do I do to configure so that when people click xxx.mydomain.com it goes to xxx.xxx.xxx.xxx:7000?

I am not talking about domain forwarding. In fact, I also hope to do the same for yyy.mydomain.com to link it to xxx.xxx.xxx.xxx:5000. I am running Ngnix in xxx.xxx.xxx.xxx. Maybe I need to configure something there?

You want a reverse proxy.

Add two A-records to your DNS configuration to map the subdomains to the IP address of the AWS instance. With GoDaddy, put xxx / yyy in the "Host" field and the IP address in the "Points to" field. (more info)

Since you already have Nginx running, you can use it as a reverse proxy for the two subdomains. Therefore, add two more server blocks to Nginx's configuration file. A very simple one could look like this:

http {
    # ...
    server {
        server_name xxx.mydomain.com;
        location / {
            proxy_pass  http://localhost:7000;
        }
    }
    server {
        server_name yyy.mydomain.com;
        location / {
            proxy_pass  http://localhost:5000;
        }
    }
}

You might want to rewrite some headers depending on your services/applications (more info). Also, consider to use Nginx for SSL termination (more info).
