After Effects definitely is widely used in the professional field. For example by TV channels. But of course, also motion pictures have been produced using it. Maybe not all the million-dollar productions that heavily rely on special effects but still big blockbusters. Besides, I assume a variety of software is used for most films anyway, so there may be a portion of AE (may it be small or large) in pretty much every film. You mustn't forget that there are always loads of people working on a film behind the scenes, and they also have personal preferences. Which does NOT mean WAX is used, though. 
Also, employers certainly don't find brilliant usage of free programs more impressive than brilliant usage of software they know and which means something to them. Let's try an analogy: what do you think future employers would prefer - you being able to brilliantly use Open Office, or you having some straight Microsoft Office skills. Of course the latter.
Something I forgot to mention and which makes the students' discount on Adobe software even more tempting is: 380 euros don't only get you After Effects. You get the entire production Premium suite - Photoshop, Premiere Pro, After Effects and many other great pieces of software. Heck, there's even a software included that helps you create a website for your films. One couldn't say 380 euros weren't fair. Especially considerung that for adults, it costs a hefty 2000 dollars. And they still buy it.
In an employer's point of view the more qualifications you have, the more appropriate for a job you are. It doesn't only come down to the skill you have applied for. For example, if I want to work in the economics branch and still I am able to produce video at a semi- or completely professional level, this counts as an additional qualification. The company knows: "If we ever need a visual production very quickly, and we're short on staff, then by all means we would be able to use that guy and he would definitely come in handy." Or something like that. Maybe it's a company that hasn't even got employees dedicated to digital production and so if they ever needed a short clip or something, they could use you rather than hiring an additional person.
A company or firm is all the more independent, the more versatile in talents and qualifications its employees are. And a company wants to be independent for sure.
