"In an extreme case, if there is only 1 left unvaccinated, the disease won't spread."
Vaccines don't necessarily grant immunity. They give you a 70%-85% chance to gain immunity. So even if 0 are left unvaccinated, 30% of the population has no immunity.
It is unlikely to infect a large portion of the population, but especially for vaccines which are only 70% effective, it's highly likely 1 or 2 others will get infected who were vaccinated but it didn't take. In addition to the 30% of people who do not have immunity, immunocompromised people often time can lose immunity to certain viruses based on their condition. They are the 1 or 2 people our society has chosen to be effectively infectable in spite of vaccination. That's why its very important everyone else gets vaccinated.
The likelihood of a huge outbreak is still relatively small, but you're wrong on the statistics of the small infection, as you'd see from a friend coming by or out to dinner with you or going to day care. Roughly 15% to 30% will get many of the diseases when "intensely exposed". The chance of a small outbreak is moderately large with 70% vaccines and even moderate lack of vaccinations.
Your argument, in addition to be attempted technical nitpicking which is wrong, is very dangerous as other posters have made. The effect of one additional unvac on a given population is extremely noticeable on small populations, such as groups of friends and daycares and businesses, aka the very places I suggested ostracizing people from.
