I see why your explanation is being questioned. You talk about determinism following from being able to model if particle X with mass A collides with particle Y with mass B we can figure out what happens. OK, so far that's fine. Let's say particle Y goes into a black hole and information about it was lost. How that does that make the outcome of the collision that preceded particle Y going into the black hole non-deterministic? Particle X is still going to fly off where it did because that happened prior to information about particle Y being lost.
What this would do is eliminate the ability to "rewind time" and figure out why particle X is where it is, which may indeed matter in some more modern theories but in classical determinism it does not.
Classical determinism says the universe is essentially like a billiards table, so if you know the initial state of all particles (balls) in the universe (on the table) and move one with a specific mass in a specific direction and with a specific velocity and specific spin, you will know what happens to every particle (ball) in the universe (on the table) since their interactions with each other happen according to known laws of physics. In this model a particle going into a black hole is no different than a ball going into a corner pocket. It had its effect on the determinism of the universe/table prior to that time, but once it enters the hole it ceases to exist and all information about it visible to the universe / to the pool table is erased.
