I fully believe this sentiment and support it as the healthiest approach not only to writing but to any skill where there is a percieved "talent" barrier to entry. I've met many people who have given up learning to write, learning an instrument, learning to code, or any other task because they believed themselves to be lacking "talent" and therefore couldn't start learning. In reality, talent only makes the the start of learning a skill less rough but it does not provide anyone with mastery. Only practice and work can give you that, and practice is something absolutely anyone can achieve.
