I've spent many decades going into the back country in the west, and not even seen a bear or mountain lion in the wild. And only ever seen 3 rattlesnakes. There is some good info in the links below.

What happened in the Colorado Front Range, is that over the past 30 years years or so, people have steadily built houses in the woods, which caused the authorities to outlaw hunting in those areas. Therefore, the deer population exploded in those areas, and the mountain lions moved in behind them. Those 2 incidents I cited were in that same area. I was mainly indicating the typical mode the lions use for hunting.
You can be pretty safe camping in the woods if you stay in NF campgrounds where other people are also camping. And of course, not too many mountain lions in desert Arizona.
