Come across terms like 1024 resolution radio. What does this mean to the user (Understanding for dummies type of explanation expected)

1024 (10bit) is the resolution of the joystick, i.e. the total traverse/1024 is the least movement of the joystick the radio can sense

Note this... you will not need or feel the difference between 1024 and 2048 resolution, unless you are a (top level) competition flyer.

So it seems. On an average the end to end movement of the joystick is few inches. I wonder how can someone differentiate likes of 200th of an inch movement..... simply mind boggling

Its really a new thing to know about..
Even i appretiate the people who can make out and sense such a fraction of inch. 

Actually this comes when the signal data of each channel goes digitally through RF and after receiving, it regenerates in analog mode. So, this is for digital system.

But what about analog system ? A 2mSec  or 1mSec pulse contains signal ups and downs and the Data can be stored for 72MHz = 72K peaks in 1 second. So, you may treat the resolution is 72K/2 = 36k. But simultaneously, the data is more reliable in Digital system than analog one.

HAMs can explain more. Thanks.

72 MHz ( or 40, 35, 36 etc.) is the carrier  frequency and has nothing to do with the frame rate or resolution.

Frame rate is usually 50 Hz, i.e. the data for all channels is transmitted 50 times per second.

Resolution is relevant in digital systems. The total possible travel is converted into a number of finite steps which is the resolution. the first digital sets had 512 steps followed by 1024 and now 2048.  Each additional "bit" doubles the steps. Personally, I doubt that even experts would be able to resolve a few microns of movements with their thumb.

With higher resolution, all that even the experts say is that they "have a more connected feel".  So it could be just a "feel", proportional to the money paid !

I personally feel that  the servo speed and resolution would be the biggest factor in the overall (from a particular input through to movement of the control surface) response time and accuracy.
