the wave function never really stops being a probability. you can collapse it down to basically a delta function but never to an exact point. and even if you could collapse it to one point itd still technically be a probability, just that 100% of the probability distribution is located at one point.
and yes, as soon as youre done measuring the particle or whatever, the wave function begins to "widen" over time as per the schrodinger equation.
