Similar? Yes.
Noticeably different? Yes.
Now let's look at where animations are irrelevant.
Zandalari female and a troll female.
Just reskins.
Different dance animations.
If you had logged into the game and saw the two models dancing side by side, but differently, you would not know which is which without being informed before hand. This is literally how irrelevant animations are, they come after the fact, and are not used as a means of differentiation because every race you use in this game is a humanoid and capable of the same movements.
This is literally how the brain is hardwired dude.
We don't care about animation of the body outside of determining if its male or female.
I can disagree because of science and game design. Animations mean nothing.
People STILL think that the zandalari male troll uses a night elf model because of the way they both wave, even though the two use different models. Animations don't create racial differences.
The actual race itself is the difference.
No one goes "i know its a nightborne because he stands different from a night elf", he goes "thats a nightborne because of his anorexic and terribly proportiioned body."
They go "thats a nightborne female because her ears and body proportions are different" not "SHE STANDS WITH HER KNEE EVER SO SLIGHTLY BENT!"
poses mean nothing dude.
In the era where animations needed to be done cheap such as everquest, the only reason you knew an orc was an orc was because he looked like an orc.
Height was different.
You know...appearances and proportions, not animations.
