On “What are pointers?”
No difference, only syntax.
I like to stick my ```*```'s on the variable name like
char *foo
or when casting
(char *) foo
Here's a very professional video explaining pointers

You should have put more thought into the picture he made. Here’s some background:
Prerequisite: link to this video
Those boxes separated by the |. | are single spaces in the array allocated. Above the array picture, they are labeled with their indices (starting at 0).
Those arrows represent something important: it is called a pointer. A pointer is a value, like an integer, or a long; a pointer is the value of a memory address. So, an array is stored in memory, likely in the stack memory.
Let’s say you have the argv pointer array, char** type. This is an array of char*, char* is a pointer; char** is a pointer to an array that contains char* pointers.
So, the diagram starts at argv, the char**. A…

…allocated as one large blob of memory where the blob contains N slices, so if the memory starts at address M and each block is 100 bytes:
M\0\
M\100\
If you wanted to always have a pointer at the first two, perhaps they are important, you can assign:
M\* ptrM0 = &M\0\;
etc. Still on the crziewst videos but it's still relevent!

On “What the fuck is the use of a pointer??”
Imagine you put something in your mailbox. You now have data at your address, to access that data the post office needs to go to your address. Going to an address to obtain data is essentially the use of a pointer
