There are two explanations for that and they are both likely factors.
First, in areas where tornadoes are rare there is less tornado preparedness, and some people might not know to take shelter, especially if there are no sirens. Some people might not even take warnings seriously, believing that a tornado couldn't actually happen in their area. By contrast, in many parts of Tornado Alley tornado drills are almost as routine as fire drills.
Secondly some of the less tornado prone areas, such as the northeastern United States, are more densely populated than the largely rural Tornado Alley, giving tornadoes a greater opportunity to cause fatalities.
Yes. F1 tornadoes rarely kill, but deaths have been recorded. In all they account for about 4% of tornado deaths in the United States.
F1 tornadoes rarely kill, and when they do the death toll is rarely higher than 1 or 2. However, the deadliest F1 tornado to occur in the U.S. since records keeping began in 1950 killed 16 people. The deaths occurred when the tornado capsized a boat on Pomona Lake in Kansas. A similar, but far deadlier case occurred in China in 2015 when an EF1 tornado capsized a cruise ship on the Yangtze river, killing 442 people.
Countless thousands. It is doubtful that data is kept on this. Most tornadoes are weak and rarely cause deaths or injuries even when they damage property. Looking at data from some of the worst tornadoes, such as the Joplin tornado, the number of homes damage or destroyed is far greater than the number killed or injured.
Oklahoma is in Tornado Alley. Tornadoes rarely affect Nevada.
stimulation rarely occurs.
Systemic
Kansas. Kansas is one of the most tornado prone states while Rhode Island rarely gets them.
Technically, a gustnado is not a tornado as it does not connect to the cloud base. Gustnadoes are comparable in strength to EF0 or EF1 tornadoes and rarely, if ever, kill.
The chances of a tornado hitting you are low. Most tornadoes are small and even the largest are rarely over a mile wide. That may seem large, but it it is still small compared with the total area around the tornado.
People rarely die during Qudditch and any deaths were unknown.

No, a hurricane is not a tornado over water. A tornado and a hurricane are quite different. A hurricane is a large-scale self-sustaining storm pressure system, typically hundreds of miles wide. A tornado is a small-scale vortex dependent on a parent thunderstorm rarely over a mile wide. A tornado on water is called a waterspout.
