It gets hard for me to keep what is said in the books and what is said in the show separate, so the following is definitely in the books, not sure if in the show:
Winter is an event that reoccurs in westeros, but it's not seasonal. The summers a long, spanning years and sometimes even decades, but winter always comes.
Many, many years before the events of GOT, there was a great threat that almost ended the world. The assumption is that it was something like the apocalyptic threat we just witnessed in the last episode. Azor Ahai is the hero that prevented the end of the world of man.
Now, the big difference between the show and the book is that there is no night king in the books and I doubt that there ever will be, as I think the books will treat this more as almost a natural disaster than just setting up a big bad antagonist like the show went with.
I cannot remember if the show talked about previous battles against the Night or the winter, but I am pretty sure it did. How did those battles resolve without killing the night king? We saw how he was created. It doesn't make sense that the children of the forest would make another night king after the first one was stopped, so if the show did reference previous battles against winter, which I am positive that it has, (otherwise how do you explain the wall?) then how do they explain winning those battles without killing the night king?
Good post and it's been a couple years now since my last read through (I read the series first after season 4 which I binge watched; then again for season 7), so take the following with a grain of salt.
Show has the single magical big bad (Night King); books have the white walkers as a collective.
The "long night" is what you referenced with winter lasting lifetimes, ice spiders, mothers killing babies before they could starve and death walking (WWs). It was ended by AA and the Wall was built by Bran the Builder (Brandon Stark) to keep the evil north, but the specifics have been lost - that was 2000 years before Aegon's invasion. Current magic is obviously nowhere near as strong or at least understood as then.
So the primary difference between then and now is dragons which at the time of AA and Bran were only in Valyria and I'm not sure if they were "domesticated" yet. My assumption is the first dragons Aegon brought kick-started the magic in the north and the white walkers have been rising since then. As the dragons died out, the magic dwindled, but the red-tailed comet and Dany's dragons being born really got them going. Mance felt it before the rest of the NW and went north to save the living, but thought the only way to get them south was militarily.
I'm guessing that Jon's resurrection and after-life will be more magical in the books (he was a warg with Ghost there too). He'll likely kill Ramsey and free Mance in some version of the BOTB uniting the wildlings and north. I do think Dany defeats the slavers (we're close to that in the books) and leaves Slaver's Bay. I also think Jon convinces her of the threat and she comes north.
That gives you magical, resurrected, warging Jon; magical 3 eyed crow; dire wolves; Valyrian steel swords, dragons and the horn of winter on one side (not sure about Arya here) and a bunch of walkers with minions on the other. There's also some story going on at the Citadel with the faceless men and Sam about to arrive which I think plays more dramatically in the end game (maybe he answers your question and they find another big magic).
I do think that based on episode 3, that the end game is a world without the Wall (that evil addressed), but the path will obviously be much different.
