Is it realistic for ordinary young girls to travel to Tibet alone? Why?

If you choose to enter Tibet by train instead of going to remote places, you will be safe as long as you go to some mature tourist routes and scenic spots, especially Lhasa, where armed police are everywhere, which is very safe. Go to Lhasa for a few days and then come back by plane or train. There will be no security risks.

If you drive by car or take the Sichuan-Tibet line, the road conditions on the Sichuan-Tibet line are complicated, and landslides may occur along the way. These are irresistible natural factors, so I suggest you take a go on road trip organized by a regular outdoor club. There may be looting in some sections of the Sichuan-Tibet line. I suggest you go with many other tourists.

In addition, be careful not to show off your wealth or be too ostentatious. For example, if you expose your expensive camera or cash, the security in the border areas of Sichuan and Tibet (Litang to Batang) is not very good, and tourists are often robbed. Hikers had better cycle through this area. It seems that Tibet is the place where girls travel most with single backpacks. So Tibet is still very safe.

The last safety issue, which is a relatively high response, is that there are generally fewer trains entering Tibet and there is an adaptation process. Moreover, the train provides oxygen, and it is easy to cause high reaction when the plane enters Tibet. As long as you don't catch a cold, high reaction is easy to deal with!
