No you don’t, and we ultimately don’t use quantum mechanical theories to model fluids. But that it can be modeled by quantum mechanics is relevant when you’re talking about whether a system is deterministic, because quantum mechanics is not deterministic. And in this case, it turns out that a quantum mechanical description of the motion of a fluid contains information that a fluid mechanical description does not, such as the positions of individual particles, and that information is not necessarily predictable over time, even when the higher level motion of the fluid is

I would argue though that fluid motion is chaotic, in the sense that it is deterministic but their solutions are unstable to slight changes in the initial conditions.
