It really depends on the organization. But in general, it's expected that you take some level of ownership over your own training. On the other hand, it's impractical to expect that people will know every element of your technology stack. Most of the time, it's expected that you know the core of the technology stack (like the programming language), but it's ok not to know every technology. And even then, you're expected to be able to get up to speed on what you don't know quickly and without sucking up too much of your peers' time.
