Answer:
False
Step-by-step explanation:
It is false because you can practice improv by just acting as you go with someone, or putting on shows where there is no script, there is a theme, and you just sort of have to go with the flow. So you can practice and learn to be an improv actor through practice. Not all actors who have the ability to be an improv actor naturally have that talent, some just have to practice and get better at it.
