it's unlikely to make you sick every time, but when it does make you sick, then it has the potential to make you very sick. Depending on which kind of meat/microbes+parasites, it can be fatal if you don't have access to antibiotics, etc. So most of the time they would be fine, but some of the time it would be a contributing factor to their shorter (compared to us) average life expectancy

When you look at animals that that do eat raw meat, it's super common for domestic animals (ie, those that live on farms, in zoos, etc) to have longer lifespans than their wild counterparts, in part because the meat they eat is less likely to have parasites and high-risk microbes than meat in the wild. So even when a given species is adapted to eat raw meat, it still comes with risks.

But beyond that, modern humans are less well adapted to eat raw meat than our hunter-gatherer ancestors. That's not to say we can't, we obviously can. But IIRC (I'm not an expert, I might be getting this wrong), the advent of cooking our food was like 1.5-2 Million years ago, more than enough time for us to have evolved changes to our digestion and parasite/microbe resistance that make it less safe for us to eat raw food.

And since cooking takes extra time and effort compared to eating food raw, presumably the reason that our ancestors bothered is because it conferred some advantage. One of the most likely advantages that could have been is that it made meat safer
