High-performance device drivers are written in assembler, so that should not come as a surprise. Most professional game development, as well as semi-pro (unpaid) projects, is being done in C++ and a variety of tool/library-specific scripting Languages (for graphics, sound, etc.). Some amateurs have written games using MS-VB (which you'll note is missing from the list), but that language is really not suited to the task (or any truly serious work as it generates slow, bulky progs that are hard to maintain). But it's often the only language the programmers know (or own), so they use what they have (rather than be smart and learn a more advanced and truly useful language -- like C++).
Three-quarters of the Languages Mose cites are mainly used for DB connectivity or web-related scripting. Activities that are not really relevant to discussion of what are good Languages for game-related development.
The best language for cross-platform work is Java, assuming top performance is not an issue. If performance is an issue, C++ is then your best choice.
Of course, this entire topic is as likely to provoke an argument as discussing which political party can best represent the wishes of a nation. In other words, you'd do well to do your own research rather than accept what someone else says.
Statistics *always* lie. The only question is ever: for whom/what do the results favor? Only after you can answer that question can you then have any hope to derive meaningful value from any statistics ...
