It's not that hard to get into if you live near a climbing gym.

You can start in the gym. As you make friends with other gym climbers, you can tag along with them for outdoor climbing trips. I started with just a harness, shoes, and a gym membership. When I started climbing outdoors more often, I bought more gear gradually, and gradually learned more techniques from other climbers. Then I was able to take new people out, climb internationally, etc.

Outdoor climbing is more dangerous than gym climbing, and requires more knowledge. Not everyone starts climbing in the gym, but you'll want to go with a more experienced climber your first few times outside either way.
