I believe it does matter. For example, if the tip diameter is too small, then the ferrule material used may not be sufficient to withstand the force of impact with the cue ball and may crack. I believe that is why snooker cues have brass ferrules. If the diameter is too large, then the ferrule will weigh too much and may cause unwanted deflection (effective mass). That is, at some point [based on the size of the tip] the shaft/ferrule becomes either too small or too large to be useful for standard equipment.
In the range of (say) 11mm to 15mm, I don't think it matters much, but outside that range, you may encounter some issues.
