"No, I don't suppose I'm so much a collector sort of person"

Tom Felton's quote suggests that he is not a person who is particularly thinking about collecting things. He suggests that he does not have a strong desire to acquire and save items, which he is not especially enthusiastic about gathering. This might imply that he is not a person who is particularly materialistic, or that he does not have a strong interest in gathering items for sentimental reasons. It might likewise suggest that he is not an individual who is particularly thinking about gathering items for financial investment purposes. Whatever the reason, it is clear that Tom Felton is not a collector sort of person. He does not have a strong desire to get and store items, and he does not have a strong interest in gathering items for any particular purpose.
