It suggests that it is likely to be molecular.
You need to be extremely careful about making generalisations like this. They can be useful in certain cases, and they can serve to illustrate certain basic principals of the "like dissolves like" type.
However, these sorts of generalisations can lead people to have some serious misunderstandings. For example, believing that easy dissolution in water indicates ionic bonding can lead you down all sorts of wrong roads. Sugar - is that ionic? What about ethanol? But they both dissolve in water very easily!
However, in terms of this question, the fact that the substance dissolves in benzene but not water suggests that it may be composed of non-polar molecules, and therefore is not an ionic substance.
