The issue is due to how certain terminals work. In particular, sakura and gnome-terminal (Ubuntu's default) which I have used before do not register the terminal. There is, in fact, a bug report for gnome-terminal, which is closed with WONTFIX status.
Finding number of open terminal sessions, therefore, should be focused on finding parent processes of shell sessions or associated pts/tty devices, as shown in this question:
$ ps -eo tty= | sort -u
The only issue with this command is that it should display processes from all users. My personal approach would be to filter out my own processes ( i.e. terminals I opened myself ) via -u option and parse with awk:
# Note that this includes tabs as well, not just open windows
$ ps -u $USER -o tty | awk 'NR>1 && $1 != "?" {a[$0]++};END{for(val in a) print val}'
