Tor browser's parent's PID is 1 (systemd) in linux

When I open the tor browser (linux version) via the .desktop file it provides, it shows the tor browser’s main process (firefox.real) has the systemd (PID 1) process as it’s parent. The .desktop file will run start-tor-browser bash script via “sh” with some other parameters.

When I start tor browser using the start-tor-browser bash file directly, it shows the bash as it’s parent process.

Is there any concern about security when having the systemd as it’s parent, or is that more secure than having bash as the parent process? I would like an answer along with an explanation also.
