A port is a way to identify a specific process to which a message is to be forwarded when it arrives at a server. Also there can be only one service (running service) that can listen on a particular port.
As your mariaDB server is running on port 3306, any MySQL Client would establish the connection via the port 3306.
So there is actually no load involved on a port while initiating a connection to the server.
