gdscript doesn't have the number of formatting options that python does, so for something like this you have to do it yourself, either through math or logic.
with logic is easier, you test wheter the number is higher than a number, like if the number is higher than one billion, then you have to combine the variables with text, for this you use the + sign to concatenate words (is that the correct term?) and the str() function to convert variables to text. finally, before printing your number, you reduce it to something smaller with simple integer division.
if money > 1000000000:
$myLabel.text = str(money / 1000000000) + " whatever this is"
elif money > 1000000:
$myLabel.text = str(money / 1000000) + " million"
