Does that mean it's harder to tell where something is if you know its temperature?

Well akshually...
...what is measured is the average kinetic energy (mass times speed squared divided by two), so if you multiply by two times the Boltzmann constant divided by the particle's mass and take the square root, yes, you do get the particle speed (assuming all the particles have the same mass and speed, which they don't lol)nice meme tho
Actually actually Temperature is expressed as the inverse of the rate of change of entropy with internal energy, which in normal materia in normal states translate to average particles speed, but in extreme cases entropy can start to decrease with increasing energy and vice versa
Yep, entropy is the key word here. Amount of different possible states -> "random" vectors of inertia + particles speed -> higher temperature. If all the particles were going in the same direction -> lack of different states -> low entropy (which can still be high energy, but measured as low temp). AKA what laser cooling does.
I'm taking cell biophysics right now and your comment is triggering me.
