I'd identify two key reasons.
Fear and statistics
Even assuming the numbers you posted are true and accurate, "how safe people feel to walk alone on the streets at night" isn't the same as "how likely are you to be murdered".
As a general rule, you are more likely to be murdered by someone you know. Here's the FBI's Crime in the US 2019 Expanded Homicide Data, showing that out of the roughly 50% cases where the offender is known, 20% (which is about 9.9% of those 50%) were strangers. Previous years show similar numbers, and there weren't more up-to-date numbers.
The point though isn't to be extremely precise. Numbers might vary from country to country, by gender, and by a number of other factors, but in general, it's true. You are more likely to be murdered by someone you know. A lot more likely.
But is it what you fear? Probably not. Without going deep into psychology, humans have a tendency to be more afraid of the unknown, and "walking alone at night" is prime overactive imagination, "I'm gonna get murdered by a serial killer" dubiously-rational fear territory.
Media coverage
Not all crimes get coverage proportional to their statistical occurence or likelihood.
This is true for both news reports, there is after all an economic imperative to generate views which tends to favor more spectacular reports.
This is also true for fiction, there are for instance a lot more police procedurals and other crime dramas featuring homicide detectives than FinCEN analysts.
Imagery of violent crime perpetrated by random strangers is probably going to have a more powerful influence on your fears than a pie chart from the FBI.
