Not necessarily. A 102 will usually show around 25 to 35 Ohms impedance. The Vswr will look good and long range will be easy. The 50 Ohm is a free space figure.
To be Honest the only 50 Ohm antenna I have ever seen was my old co-phased 102's on my old Dodge Carryall. The thing to worry about is just the Vswr. As long that is low you are in good shape. Don't too much about all the other readings. They are not of much use to you unless you are going into design and research.
some interesting reading about resonance and where the XL and XC come from in your analyzer.
