This meme is about the difference in scales. When your electron’s delocalization is much greater than other scales in your system, the electron behaves like a wave. Otherwise if the electron’s delocalization is the smallest scale, it behaves like a particle.
If you can look at the setup of an experiment with your bare eyes, the electron behaves like a particle. If you cannot - it may behave like a wave.
You can see wave properties from a double slit setup with your bare eyes. Here’s someone who did it with a cardboard box.

If you setup a detector that measures which path the particles took, the interference pattern disappears- again something you can see with your bare eyes.
For electrons you can’t do it. Either way the interference is not a quantum effect and the detector that you are talking about is a simple reemiting device that detects the wave vector and creates the wave in the same direction. Now live with that.
For electrons you can’t do it.
