At this tiny scale, energy and mass are essentially equivalent. So when we say that matter annihilates, we mean that they transform into pure energy (in this case, as photons of light). They don’t break into subatomic particles, because that still counts as mass. They just simply cease to exist.
As a side note, the “conversion rate” of mass into energy (and vice versa) is governed by Einstein’s E=mc^2. All this equation means is that it takes a ridiculous amount of energy to create a small amount of mass, and vice versa, it only takes a small amount of mass to create a ridiculous amount of energy. Because antimatter annihilates completely (ie, 100% of its mass, as well as 100% of the regular matter’s mass, gets converted into energy), antimatter is currently the most explosive thing known to mankind
Man that’s pretty wild to think about. If antimatter was created at the same time as matter in the same quantity and distribution, then why are we here. Why didn’t the entire universe essentially cancel itself out? Was there some factor that benefited regular matter or hindered antimatter? Is there some level of chaos on the atomic or subatomic scale that played in regular matter being the dominant? Has some crazy philosophical implications.
I mean if you just thought of all those questions on your own, that’s damned impressive. You just summarized one of the greatest mysteries in particle physics. Here’s a story about that exact question - what was the process that gave preference to creation of matter over antimatter?

Ok that makes sense.
