There are multiple interpretations of quantum physics. According to the "many-worlds hypothesis", the randomness is also deterministic -- it means that the reality branches into multiple futures, different futures containing different outcomes. Here, randomness means that you cannot predict the outcome, because in the future there will be multiple copies of you, and whatever specific outcome you predicted, some of those versions will see a different outcome. But at the same time, this is fully deterministic, in the sense that there is an equation that describes exactly which futures will happen and which outcomes they will contain. (There are also other intepretations, which add a new assumption on the top of this, such as "and one of those futures, selected randomly, is the real one, and then the remaining ones disappear". Which is kinda unfalsifiable, because yeah, it could be like this; but it also could be that all the different futures are equally valid, and each of them contains a copy of you saying "oh, so this one is the future that actually happened" -- but of course, different copies of you saying it about a different version of the future.) EDIT: However, from the perspective of the "many-worlds hypothesis", everyone has an infinite number of futures... so the statement in the article doesn't make sense here either. So, I am going to assume that the paper actually referred to something else, and the author of the article, trying to simplify it, turned it into something nonsensical.
