pl.count() has changed since 0.19.8 and 0.20.31, it now does not count null values, hence why it is returning a smalling number.

0.19

Count the number of values in this column/context.
Warning
null is deemed a value in this context.

0.20 (stable)

Return the number of non-null values in the column.
...
Calling this function without any arguments returns the number of rows in the context. This way of using the function is deprecated. Please use len() instead.

Ah ok, yea that's probably the issue. I'll close this then
