Since lens with high focal distance are generally not that fast and they need high shutter to freeze moving animals, how do they get light without addind too much gain an grain ?

Daylight generally provides enough light for the job.
Additionally, depending upon the animal you’re taking pictures of, shutter speed likely doesn’t need to be above 1000/1500. Most animals are not moving around at full speed all the time.
For birds in flight even, I shoot around 1/1250 or so. Exceptions would be hummingbirds if I want to stop wing movement, that’s at least 1/2500 or a bit higher.
And equipment can make a big difference. For serious professional shooters, they may have a fixed aperture of say f/4 or f/5.6, which is excellent. A budget lens can be several stops more which would cause challenges, particularly at dusk/daybreak.
