If you forward a port on your network (or VPN) and point your torrent software towards that port, you are now an “active” node. You can communicate with anyone else, forwarded or not.
If you leave it closed (passive node), you can only communicate with active nodes. With large torrents, this isn’t an issue because there’s more than enough active nodes to send the data.
Port forwarded: talk to anyone, even closed
Port closed: only talk to port forwarded people and hope that small torrents have someone with a forwarded port.
Not typically but it can vary depending on which protocol and which provider you use. Best to check yourself using something like ipleak.net and see if there’s any identifying info on there while you’re connected.
If you don’t have port forwarding and the seeder doesn’t then you won’t see them.
A lot of casual torrent users won’t know about this so it’s a common issue on public trackers.
Could you elaborate? Never heard of this aspect

Thank you. Does this create any considerable vulnerabilities?

That’s great. I’ll do some more research on the hardware I have also
Did you mean if there is no port forwarding at my end and also at seeder’s end ?
Yes, to communicate at least one peer needs to be port forwarded.
