What tacit knowledge means differs by whom you ask, but in general the definition refers to knowledge that is very hard to acquire (In the broadest definition) or knowledge that is embodied in a person (or group) and that they can't make fully explicit. Of importance here is that talking to an expert wouldn't get you that knowledge, in this second definition. An obvious example is riding a bike; one could read books about cycling or talk to Tour de France winners for months and not have much idea how to skillfully ride a bike on a first trial. Tacit knowledge may be hard or impossible to get from experts, but this is not that bad: one doesn't need this tacit knowledge for many purposes. If all you need is a precise answer to a question, asking a panel of experts (if they agree on the answer, at least) can yield a reasonably trustworthy answer even if we are not fully aware of the chains of reasoning and specific pieces of evidence the experts are relying on when delivering that judgement.
