Priority of a message during network overload?

You are a bit confused.
The content (or the text) within packets does not influence the priority of service.
Packet priority is based on the protocol of the creating application.
For instance, top priority for Internet transmission/reception is given to things that would be adversely affected by latency, such as Voice over Internet, or gaming over Internet, or other things needing the best possible speed.
Mail, FTP, http, and so on can afford latency and so take a 'back seat' as it were, allowing those transmissions with priority to be handled first.
This ties in with the QoS (quality of service), a setting within routers, or other LAN hardware items.
