Yes and no. I have a Prusa Mk3 that I've had for years and upgraded to the MK3s. The machine was flawless from day one even in the hands of a complete novice like me. The upgrade was also flawless. This times I've had bad prints? I changed filaments without understanding how it behaves. I printed things without understanding how to prepare the print, and it fell over. Attempting to print flexibles. These issues may or may not plague you depending on your use case. I mostly print mechanical parts that I design myself. And I use limited types of filaments for prototyping. So can I get 100 out of 100 successful prints? Yes, that's quite achievable.
