You would lose that bet....badly. Not only due to the fact that EVERY USSS will be on a protective detail during their career, but even those in Investigations are pulled out for protective assignments.
While the President has his protective detail, additional USSS agents are deployed whenever he travels. USSS agents all go through a protective detail phase of their career. USSS provides a protective detail to the current President and VP and their families, as well as former Presidents and Vice Presidents.
For example:
Trump visits El Paso, not only does his protective detail go, but additional USSS agents are pulled from other cities. They provide additional layers of security, often hundreds of yards away. Meanwhile, Melania has her own detail, as does each of Trumps kids.
