Does pfSense automatically create a firewall rule when I set up port forwarding?

Yes, as long as you leave Filter Rule Association set to Add associated filter rule when creating the NAT rule. pfSense will generate a matching WAN firewall rule automatically. If you change this setting or delete the NAT rule later, the firewall rule will be removed as well.

What’s the difference between the NAT rule and the firewall rule in pfSense port forwarding?

The NAT rule handles the address translation — it redirects traffic arriving on a WAN port to an internal IP and port. The firewall rule controls whether that traffic is allowed through at all. Both are required for port forwarding to work, which is why letting pfSense create them together is the easiest approach.
