Repository is a collection of artifacts (eg: jars). You can think of it as a mere storage / cache of various artifacts. Dependency is a situation where your project dependent on another artifact to perform its task (eg: compile, run, unit test)
A repository in Maven holds build artifacts and dependencies of varying types. There are exactly two types of repositories: local and remote: the local repository is a directory on the computer where Maven runs. It caches remote downloads and contains temporary build artifacts that you have not yet released.
There are 3 types of maven repository: Local Repository. Central Repository. Remote Repository.
Maven local repository keeps your project's all dependencies (library jars, plugin jars etc.). When you run a Maven build, then Maven automatically downloads all the dependency jars into the local repository. It helps to avoid references to dependencies stored on remote machine every time a project is build.

On a maven project you typically declare what artifacts you need on the <dependency> section of your pom, and you can also declare what repositories maven should lookup the dependency from at the <repositories> section.
By default maven will lookup the artifacts on the central repository. But it's common for an organization to have an internal repository containing in-house developed artifacts. Hence typically <repositories> section on the pom is configured with this.

The repository is where your libraries (aka artifacts) are stored. Dependencies are the names of the libaries that your corrent project depends on
