My top 10 most used commands

I read Garron’s article about commands usage and run same command below.
history | awk '{print $2}' | sort | uniq -c | sort -nr | head -n 10

Here is the output for the private machine.

630 g
285 ls
153 cd
114 vim
109 docker-compose
93 python
88 tig
51 ll
37 npm
36 git

g is an alias of git. The output looks fair enough. wondering why ls is more used than ll tho.
