Yes - that is factual. It doesn't mean that it can't have deep signifigance for people who have either grown up celebrating it or who have adopted it as a holiday for their children. As people frequently like to point out - the major christian denominations "stole" most of their holy days from older religions - as some neo-pagans take commercial Christmas songs and re-work them as "Solstice Carols" or "Yule Carols"

everything was newly invented at some point.
