You're Correct!

All players will have a natural shot shape which they are comfortable using with all of their clubs.

To find your own shot shape, hit balls at the driving range to targets and see which way they move through the air. If they move from left-to-right, a fade shot is your natural shape. From right to left, a draw will be your most comfortable shot. Some players will hit balls to targets and the ball will travel dead straight, these are the lucky players whose natural shape is straight!

To hit straight shots, the club face will travel on an inside-to-square-to-inside swing path with the club face square to the target line at impact. To hit a fade, the club will have to travel on an out-to-in swing path with the club face open to the swing path but slightly closed to the target line. To hit a draw, the club will have to travel on an in-to-out swing path with the club face closed to the swing path but slightly open to the target line.
These paths are nothing to worry about when hitting your natural shot but can be used to adapt your swing to shape the ball in different directions.

Some players struggling with a slice are unlikely to conquer and ingrain a natural draw shape into their game without a massive amount of practice and the same can be said about hookers of the golf ball. If you hit a natural slice or hook, practice on grooving the ball flight most similar. A slicer should try to groove a fade and a hooker should try to groove a draw.

Like most things in golf, nothing should be considered permanent. Ben Hogan struggled horribly with a hook during the early part of his career but practiced so hard he hit predominantly a small fade by the end. Practicing swing path and club face angle can improve your natural shape.

Dont worry about what people say or how you perceive your natural shot shape. Use it, groove it and gain the ability to hit consistent shots.

Even beginner golfers will have a tendency to shape the ball through the air but striking the ball out of the toe or heel could cause strange shot shapes to occur. Practicing with some impact tape on the club face and checking which way the ball flies from the center of the club face will help give you a better idea of your natural shot shape.
