This is how in brings better typography:

Tabular Figures (tnum) displays numerical digits (0–9) in the same width, like in monospace typefaces. For example, the digit 1 would take the same space as 2, 3, 4 or 0, so the number 1111 would take the same space as 2340.

Tabular figures are useful in aligned columns, like in tables or price lists, as they allow users to easily compare values vertically.

Fonts that have this feature includes Inter and Rasa. Try them with text like 11,150,110 and 11110000.
