So, if such situations were "highly unlikely" as you stated, there
wouldn't be much point in providing such a simulation, would there?

They are highly unlikely outside of heavy traffic areas, both in real
life and in simulation.

However, as a general rule, simulation provides for broader control of
circumstances than real life provides, precisely so that extreme and
improbable situations can be simulated for practice. A commercial
pilot may fly for his entire career without experience a failure of
all engines at the same time, but it's very easy to simulate, which
makes it possible for him to practice and be prepared for such a
situation should it ever actually arise. That's one of the great
advantages of simulation.
