I have read all the old chem community posts and still cannot seem to figure out the difference. Does anyone know any good instructional videos or pictures to teach me?

To simplify things, just by looking at the structure a molecule with iso- in it sort of has a "Y" branch in its structure, while neo- has a triple branched structure.
If you search images of isopropyl and neopentyl, for example, you can see these structures.

Building on that, the "Y" (iso-)/ "triple branched" (neo-) structures occur at the end of the substituent.
"Sec" and "Tert" refer to how many Carbons in the substituent are connected to the C between it and the rest of the molecule.
