Can the "escape" trajectory of a gazelle be considered random?

I was watching a video of a gazelle escaping from a cheetah and I wondered: may it's trajectory be considered random? Logically speaking, escaping in a random fashion would make almost impossible for the cheetah to predict the the next move, hence increasing chances of survival.

Do you know of any research about this? Do you think their trajectories may resembles something like a Levi flight? Also, if it's objectivelly not random, does it mean it could be predicted? How? I read the "winrate" of a cheetah is as low as 30%, if it was random wouldn't it be 50%? Gazellle is just an example of course, this may apply to every prey animal that in order to survive has to deal with outrunning the predator.

I know this may not be the correct place to ask but I don't know where this question would fit better. Thank's.
