The short answer to this question is no:
The field sobriety tests can be difficult or impossible evern if you are completely sober. There are many factors that can inder a persons ability to perform on those tests.
The officer needs evidence in order to properly arrest you for Driving Under the Influence. The officer will not rely on you simply having an odor of alcoholic beverage on your person to arrest you. He must observe you for a certan period of time, and if possible gather evidence from your performance on the field sobriety test. I have seen very few people perform really well on those tests.
Many times now the officer will be wearing both a body cam, and he will have a camera on his vehicle. Both of these items will be turned over to your defense counsel as part of the discovery process. This means that if this officer exaggerated how poorly you performed on the Field Sobriety Test than it will be apparent from the cameras that will be wathing you.
