Very low probability times massive number of stars: yes I think there will be a non-zero number of actual collisions

You are confusing one big number with another big number, and treating them as the same.

Yes there are a lot of stars. It's a big number. But there's a lot of space. That's a number that's in a whole different league.

For example, the whole solar system is about 2 light-day diameter. But it's 4 light years from the nearest star in any direction. Empty space is thus many orders of magnitude more than solar systems, never mind suns.

Sure there's a probability of a collision. But even multiplied by the number if stars, it's still really tiny.
