Help with position?

I was making a wandering humanoid script, then my brain just farted and I forgot all about positions, no errors just wanted to know if this was how you did It right.(what I mean is this the right way(xzy))

while true do
    wait(5)
script.Parent.Humanoid.WalkToPoint = Vector3.new(math.random(37,77),math.random (86,123),25)
end
