Nearly any tripod is better than nothing for the photography you mention. In fact, simply sitting your camera down on a steady surface (pole, fence or on a 'bean bag') is better than hand holding. Whether it is 'worth it' comes down to whether you will need to buy two tripods: the one you settled for and the one you should have bought.
What makes a tripod good includes it being sturdy enough for your gear, precise in maintaining the angle and shot you want, and relatively steady in reducing vibrations.
Sturdy means the legs, the head and the mount (where it attaches to the camera) having enough strength to hold your camera of course, but also other items like your camera bag. Many tripods include a hook to hang extra weight, like your camera bag from, to keep it from moving in wind and reduce vibrations.
Also, you want the head to hold your camera and lens without it moving, slipping or rotating around the screw. And you want the head to maintain the shot when you lock it down. Cheaper tripods will often 'drift' or sag when you lock down the head, the result being the framing is no longer preserved (what was in the frame of the viewfinder is no longer in the frame, as the camera moved).
The tripod you show will certainly demonstrate all these faults. It likely will suffer from vibrations, and the head will sag and drift easily. It is plastic and uses a poor quality twisty bit to tighten it down.
For an example of one that is a bit more 'worth it' I provide this link for reference:
