Not true, there are plenty of foreign students everywhere in Europe with small languages and if the program is English they do just fine. It really depends on the person. Some really cannot stand not understanding everything around them on the street, in the supermarket etc, others find it thrilling and a positive challenge to work through, they often take language courses in parallel to uni studies, but some never learn the local language and stick to international circles or English speaking locals. There are many ways and tons of people do it to their satisfaction.
