There's certainly no traditional programming required, as in typing in scripts that are run through a compiler or interpreter. That is what "no programming required" is intended to mean. However in the very general sense of programming being a sequence of instructions for a computer, events probably do qualify as that. But they're so different to the traditional approach that I think it's a fair statement.
Sometimes people come to the product expecting there to be built-in features exactly covering the specific requirements of their own game, or tutorials covering the same. There are so many different kinds of things you can make that it is nearly impossible to cover everything anyone could ever want. So we cover the basic general-purpose features, and you build the rest yourself. You still have to think about how to put it together, but IMO that makes it a more interesting product, because it's not a stamp-out-slightly-modified-versions-of-some-templates tool, it lets you build genuinely original stuff.
