A Servlet Container can be thought of as a repository for Servlets. When developing web applications with Java, multiple Servlets are needed, and the Servlet Container manages their lifecycle and provides multi-threading support. Tomcat is a prime example of a Servlet Container. Spring MVC is also a Servlet that is managed by the Servlet Container. When someone says they only need Spring MVC without Servlets, they're referring to handling business logic through Spring, not suggesting that Servlets are unnecessary.
