You left out a few facts.
"Victims are typically male and between 17 and 27 years of age." - The people trying to capture or kill them.
"A late 1950s study estimated that 45,000 snakebites occur each year in the United States.[2] Despite this large number, only 7,000 to 8,000 of those snakebites are actually caused by venomous snakes, resulting in an average of 10 deaths.[3][4] This puts the chance of survival at roughly 499 out of 500."
"Most snakebite related deaths in the United States are attributed to eastern and western diamondback rattlesnake bites. Children and the elderly are most likely to die (Gold & Wingert 1994). The state of North Carolina has the highest frequency of reported snakebites, averaging approximately 19 bites per 100,000 persons. The national average is roughly 4 bites per 100,000 persons.[4]" - eastern and western diamondbacks.
"Of the roughly 3,000 known species of snake found worldwide, only 15 percent are considered dangerous to humans.[5] Snakes are found on every continent except Antarctica. The most diverse and widely distributed snake family, the Colubrids, has only a few members which are harmful to humans. Of the 120 known indigenous snake species in North America, only 20 are venomous to human beings, all belonging to the families Viperidae and Elapidae.[5] However, every state except Maine, Alaska, and Hawaii is home to at least one of 20 venomous snake species.[6]" - Only 1 species. Not every species.
"Since the act of delivering venom is completely voluntary, all venomous snakes are capable of biting without injecting venom into their victim. Such snakes will often deliver such a "dry bite" (about 50% of the time)[7] rather than waste their venom on a creature too large for them to eat." - They will not always inject venom, and then rarely enough to kill.
"The most common symptoms of all snakebites are panic, fear and emotional instability, which may cause symptoms such as nausea and vomiting, diarrhea, vertigo, fainting, tachycardia, and cold, clammy skin.[8] Television, literature, and folklore are in part responsible for the hype surrounding snakebites, and a victim may have unwarranted thoughts of imminent death." - Panic and fear. Shock causes most of the deaths from snakebites as well.
"But like I said, I wouldn't want my kids being swamped by poisoned snakes" - Snakes breed and grow too slowly to have problems out of there being too many of them, as natural predators and keep their populations down. In fact, they are in a steady decline due to too much people. Most of the problem with them coming into contact with people is habitat loss.
