Hi,
Animation is one type of VFX. So he probably is using the terms interchangeably.
An internship can be helpful but not necessary for getting a "real" job. It will give him experience and looks good on his resume.
Tell him to ask his professor teaching the course if there are any internships that he might apply for now or after he graduates from the course. The professor is his best source for that info.
Hope this helps,
