In general, all traffic on the Internet has a beginning and an end point Often, this is referred to as the client and the server.

The server listens on well known ports. The client generally uses whatever is available.

When you run HTTPD on your machine, it is generally acting as a client, listening on port 80, or port 443 if using SSL.

When you use YUM to access their repo services, their server is generally listening or port 80, or port 442 if using SSL.

So, when you block HTTPD on your computer, you are not blocking that service on another server, like YUM, because to access a repo like YUM or GIT you are acting as a client, accessing a server. When you block or disable HTTPD on your computer, you are simply blocking access to your server, locally.

You should probably do some homework and learn some basics about client-server processes.
