Like any topic/skill, it can be learnt, but only if you spend significant time and effort by doing projects, exercises, asking questions (stackexchange, etc.). It's very important to pay attention to fundamentals and thinking from scratch rather than mastering a laundry list of tips/tricks, because fundamental ideas can be composed in different ways and adapted to a new situation. The fundamentals here would be probability, statistics, linear algebra, optimisation.
