Scary? No.
Fun? Yes!
Seriously when I first started, my instructor began with VERY basic things. Everything is taken one step at a time. I highly recommend taking up gymnastics. You should have a good time challenging yourself. Its actually quite a thrill. With doing any sport, it is inevitable to fall and hurt yourself sometimes. It happens.
Enjoy yourself!
Go for it! You will start of with the simplest moves and build up gradually and the coaches will spot you and use safety equipment like soft mats, so it is not really scary.
You'll get used to it. Don't avoid new things though, you might end up loving it!
yea it can be dangerous but tell me sport isnt
