Question about firewall rules and states

[Trust9]

Hey guys,
I don't really understand the states and the firewall rules.

As an example a pass rule for TCP port 80

As I understand it, I click on the states in the front to display all connections to TCP port 80.

But there are now also a lot of 443 UDP connections included

It looks like this for all rules.
Here port 53
There are also a lot of connections to highports in it

Am I misunderstanding this?

Thank you

Edit:
Where can i find the rule ids?
Can I have them displayed somewhere?
