Like the phones that have a special plug and everything, the cord one still work when the electricity is out and they don’t seem to have batteries in there, so how and why do they still work

Those old phone lines carry (a little bit of) power, enough for the phone.
When you have a power outage you lose the power supplied by high voltage lines to your home, but that’s completely separate from the phone lines.
