Totally disagree with this statement. It's quite normal to be less and less nervous, and more and more comfortable, as you do something more often.
First date, first day of school, first day of new job, first tryout for golf team, first amateur tournament, etc, etc, are all going to be making most, if not all, people a lot more nervous than the 2nd, 3rd, 4th, 5th etc, etc. of each activity.
You absolutely can "train" nerves.
