The first formula, ALL removes any active filters from the columnA.

The second formula, ALL returns a table containing all columns.

About ALL and ALLSELECTED, we can create a sample to help you understand.

We want to calculate the total value of the name. So we create two measures, one uses ALL, another uses ALLSELECTED.

ALL function calculates the Total = CALCULATE(SUM('Table'[value]),ALL('Table'))

ALLSELECTED calculates the Total = CALCULATE(SUM('Table'[value]),ALLSELECTED('Table'))

We can see there is no difference between the last two measures, they are both 10.

Now we add a slicer based on Name and select A and B.

The rows become two, and the ALLSELECTED measure changed.

Because the ALLSELECTED function is affected by external filters, the Name slicer is one of external filters.

But the ALL function is not affected by external filters.

If you want to calculate the total that will not change, you can use ALL.

If you want to calculate the total that will change according to the slicer, you can use ALLSELECTED.

Maybe you can refer the following video, video explanation may help you.
