The fact that it is possible to jump from MLE to a research role in Deep Learning means that this pathway is accessible to anyone who is a decent SWE and has some math skills. But there are much fewer research positions. So there is an element of luck and being at the right place at the right time.
Today, the competition for research positions in a "sexy" STEM field (think quantum computing, black holes, DL, RL) is quite high. DL just happens to be a field where it is possible to get into research without investing too much time while also making a lot of money, so this is a dream job for many.
