Not necessarily.
There are those for whom deceit and lies are part of their profession - they can and do persist at these activities without being found out. That's sort of the point of espionage in particular, where career spies conduct operations without ever being discovered. It is both effective and efficient if the individual has talent for the craft, clearing a pathway for others to make use of information obtained covertly or through deceit.
I'm not suggesting this sort of thing is sensible or desirable for non-professionals, but it is certainly a thing. Even amateurs can weave deceptions that are never discovered, often with little significant consequence. That's part of why taboos against deceit developed in the first place - it is easy and anyone can do it as well as get away with it. I doubt that there's a single human on this forum who hasn't told multiple lies and not only got away with it but faced no real consequences. In particular, making up excuses for things because our society at large expects "reasons" for everything is one of the most routine and everyday of lies.
