It does not matter because both interpritations demostrate the same principle. And Jesus did not say it was impossable for a rich man to get into heaven. He was saying that it is vary hard for a rich man to get to heaven.
Matthew 19
23 Then Jesus said to His disciples, “Assuredly, I say to you that it is hard for a rich man to enter the kingdom of heaven. 24 And again I say to you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God.”
25 When His disciples heard it, they were greatly astonished, saying, “Who then can be saved?” 26 But Jesus looked at them and said to them, “With men this is impossible, but with God all things are possible.”
