I would expect "$\sigma^2$", if this is a statistics question, to be the "variance" but then what is "$\sigma^2{X}$"? And how is $\sigma^2(x)$ a set?

A probability constant is like 1/6 on a dice, the 1 is a constant of the 6.

scenario

We have 4 sets ,{X1},{X2},{X3},{X4}

each set contains 13 individual variants, that are not the same in each set.

{X1}=13 individual variants 1a-13a
{X2}=13 individual variants 1b-13b
{X3}=13 individual variants 1c-13c
{X4}=13 individual variants 1d-13d

So if we were to pick a variant from any of the sets, each variant has a 1/13 chance of been picked of each set.

This time we will randomly pick 13 of the individual variants randomly from any of the sets, keeping the values hidden. Making a new set {Y} and then discarding the rest of the the hidden values.

So set {Y} is a mixture of the whole of {X} sets.

σ²{X}=Y

It doesn't mean anything! In particular, "1:52" is not even a number, much less a "golden constant", whatever that means! I don't know who wrote the "physicists explains" part but it also is non-sense. Now the "golden constant" apparently, again without explaining what that means, is 1/3.

I am sorry but if you know maths, you should know what a golden constant ratio is and what the symbol is.

What normally does a constant mean?

unchanging.

lets do this a simple way

f(x)=1/52

x²=52 *52 and makes a grid of x and y

f(Y)=?

added- I will draw it you using dots

f{y}=?

0.....f{x}=1/52
