At some point, you'll probably fall ag. But that happens with cages, flat peddles and clipless. It's just part of the sport. If you shop around for peddles and get some that allow loosening, you'll be fine during that learning curve. Once you start getting comfortable with them, if they are adjustable you can start tightening them. Though they aren't adjustable, I can't say enough about how easy it was to adapt to the Time ATACs.

If you have a local bike shop that rents bikes, you might be able to convince them to loan you some peddles to try out. That would also mean borrowing shoes. So it could get to be too much of a hassle. But don't let anyone discourage from going to that next level with clipless just because it might be difficult at first. We've all got scratches, bruises and scars from our various skill building exercise.
