Take a handful of marbles, and have a friend take a handful of marbles, stand half a kilometer apart, and shoot them into the air towards about a 1 meter radius sphere that would be the collision space. There's a quite significant chance, with marbles, of no collisions whatsoever. Make the marbles a handful of sand and repeat it again. Compared to the galaxies that are colliding, our own is almost 500,000 light years across. The sun is not even two light seconds wide. A direct collision between two stars in that much space is incredibly unlikely.
There will be several star-star collisions, certainly, but that's attributable to the number of stars involved in a poorly coordinated interaction. In a stable galaxy, like the Milky Way is now, star-star collisions only happen with any realistic frequency between binary pairs. Even with the destabilization inherent in a galactic merger, you NEED to keep in mind how utterly LARGE a galaxy is. To scale, our entire solar system is a tiny, almost unnoticeable dot in the empty space that is our galaxy's sphere of influence.
If the marbles also had their own gravitational that varied between sizes and density And sure the odds are low when it just begun, but the waltz of death that comes after when the two stars gravitational pull met. I'm just saying Galactic Cannibalism isn't a breeze between two galaxies meet. And your right about the massive black holes consuming the se excess. I guess two super clusters would be a little different. Anyways I'm just talking now. I'd like end it with saying this though. Sure the numbers are low compared to the vast distances of the universe, but the sheer amount of stars compared to humans. I'm sure the star casualties would be rather high.

But they do...

Stars in our galaxy are still light years apart. A lightyear is approximately 10^15 kilometres. Since its launch in 1977, the voyager has traveled about 0.002 lightyears. It travels at a speed of 65 000 km/h. The distances are just too great.

During the 90s we thought stars colliding was once in an eternity. 10-15 years later we have concluded that there're 100s of stars colliding out of sight within the vastness of the universe. Everything that we thought were uncommon are pretty god damn common. Like Earth like planet within the goldilocks zone was once thought near impossible, but a few years later were finding them all over the place as well as black holes.
Were so knowledgable with our small scaled studies and tests and conclusions based on small studies. We can only predict and stand by our odds that we found, but time and time again have I seen the odds go against people, normally it's just human error though.

Hopefully this will happen before the sun blows up everything. Either that, or we will nuke ourselves. I predict we will nuke ourselves in the next 200 years.
