Yes that's slightly better. However millions may still die even with vaccinations, because most of the world does not have access to them and they don't have adequate health care. Also, with time as mutations occur, vaccines will get less efficient.
You got confused with the smallpox. I mentioned smallpox as an example of what COVID isn't. Not every disease warrants mass vaccination, and this depends also on efficacy of the vaccine.
COVID may warrant it for specific subpopulations. But we don't have good enough vaccines yet to eradicate COVID. "Getting rid of COVID via vaccines", "vaccines is the only way" is just fantasy/propaganda tactic to increase vaccinations.
