Can I experience robotics without a physical robot?

I’ve been working with small projects every now and then. Now, I want to step my game up and gain experience with ROS. How may I do so without spending for the robot? I’ve heard about gazebo but I have no experience with it. It would be nice if someone here could point me to some good tutorials that focus on ROS using Gazebo. Thanks!
