You won't have to talk to ATC on your first lesson or trial flight. The instructor will do all that for you. Go for it, you never know unless you try. Be aware that gaining an ATPL is very expensive and jobs aren't easy to come by once you have it.
I flew gliders for years before I went onto powered and never spoke to anyone on the radio. I found converting to powered flying no problem at all apart from the comms. I well remember on my first trip listening to ATC (I fly from a full ATC field) and thinking that there was no way I wouild be able to understand all of that gibberish. But like everything else one day it clicks and you have no problem with it from then on.
