That does not mean that it is not a parable. A parable is simply a fictitious story from which a moral or religious lesson may be drawn. There is no rule that people mentioned in it can't be given a name, or that references to real places can't be used. Consider these parables:
Luke 12:16-21 (WEB):
(16) He spoke a parable to them, saying, “The ground of a certain rich man produced abundantly.
(17) He reasoned within himself, saying, ‘What will I do, because I don’t have room to store my crops?’
(18) He said, ‘This is what I will do. I will pull down my barns, and build bigger ones, and there I will store all my grain and my goods.
(19) I will tell my soul, “Soul, you have many goods laid up for many years. Take your ease, eat, drink, be merry.”’
(20) “But God said to him, ‘You foolish one, tonight your soul is required of you. The things which you have prepared—whose will they be?’
(21) So is he who lays up treasure for himself, and is not rich toward God.”
Luke 10:30-37 (WEB):
(30) Jesus answered, “A certain man was going down from Jerusalem to Jericho, and he fell among robbers, who both stripped him and beat him, and departed, leaving him half dead.
(31) By chance a certain priest was going down that way. When he saw him, he passed by on the other side.
(32) In the same way a Levite also, when he came to the place, and saw him, passed by on the other side.
(33) But a certain Samaritan, as he traveled, came where he was. When he saw him, he was moved with compassion,
(34) came to him, and bound up his wounds, pouring on oil and wine. He set him on his own animal, and brought him to an inn, and took care of him.
(35) On the next day, when he departed, he took out two denarii, and gave them to the host, and said to him, ‘Take care of him. Whatever you spend beyond that, I will repay you when I return.’
(36) Now which of these three do you think seemed to be a neighbor to him who fell among the robbers?”
(37) He said, “He who showed mercy on him.” Then Jesus said to him, “Go and do likewise.”
The first parable includes mention of God, whom I'm sure you agree is a real person. The second parable mentions Jerusalem and Jericho, which are real locations.
