Hi Welcome to the Drupal community. Some of this depends on where your interests are. Do you like to do front end development or backend? Typically Drupal contributors take a few possible paths. They might contribute a theme or perhaps a module. These are typically what's known as contrib. By contrast, some developers also contribute to Drupal core. There's lots of different paths you can take for contributing. There's a nice guide here about being a novice contributor to core. I personally did not contribute to Drupal until very recently even though I had been developing with it for several years but I have to say it's been a worthwhile experience and really rewarding.
