[Resident Evil: The Final Chapter] It seems to me, or was it already clear in the last film that Umbrella won, and it was not worth destroying her?

As far as I can remember, the main people in Umbrella decided to almost destroy all of humanity, and start over from scratch. Naturally, Alice did the right thing, which interfered with their plans, but up to the penultimate films! Because before the penultimate film, people still had some chance for the rebirth of humanity, but with their destruction (As I remember, all the strong remnants of humanity gathered in the white house) everything became meaningless, because already in the last part of the film it is said that there are several thousand people left alive (Not counting the people from Umbrella). 
Should Alice have already given up, because with the destruction of the remaining Umbrella, she will really doom all of humanity to extinction?

Alice released the cure for the T-virus into the air.  The cure destroys organisms infected with the T-virus.  While it will take years for the cure to travel through the air and reach all the T-virus creatures worldwide, the fact that the T-virus will be wiped out is a certainty, it's only a matter of time.  

How much of humanity is left?  Who knows?  It's true that the world's population has been vastly reduced, but there may be isolated enclaves or communities of people still hidden somewhere around the world, sort of like how Claire's group was hiding and surviving in Raccoon City.  Once the threat of the zombies and other bioweapons have been eliminated by the airborne cure, the surviving remnants of humanity can attempt to rebuild some semblance of civilization.  

Is it certain that humanity will survive?  No it is not.  But nor is it certain that humanity is doomed, especially now that the cure has been released.
