Yes, if you design and prototype PCBs you find pretty quickly that you don't need that many standard components. It's nice then to think about what you need again and again, and then organize it somehow. You can also just collect it over time, but then you end up with large digikey bags filled with smaller digikey bags of components, and it becomes easier to just order everything you need each time instead of sorting through it all.
