I think the per kg is important there. 192mg/kg of body weight is the lethal dose. So for example a 100kg person would need 19,200mg of caffeine to be a lethal dose.
To edit: that’s not to say that the lethal dose in this picture is wholly accurate. Caffeine has been known to cause cardiac arrest even in lower doses.

Good point, I hadn’t considered it was based on body weight, and rather thought it was just median population
LD50 is specifically a dose that kills 50% of the subjects.
Lower doses can kill, just less than 50% of people.
