When you say "people", do you mean academics, or non-academics?
Academics have talked about white privilege for decades, largely without controversy, or interest among the main population. They also talk about all these other privileges, like height, beauty, wealth, and even Jewish privilege. That's likely where the statistics in the video come from -- academics who have studied these different privileges.
So it's not correct to ask why these other privileges are not talked about, at least among academics. They are, and they have been.
Non-academics have recently started talking about white privilege, largely because they misunderstand what it is, and lately feel the need to become defensive, often painting themselves as the real victims of some unjust "politically correct" over-corrections. Maybe this helps rationalize blaming foreigners as scapegoats for some of their own problems caused by a world leaving them behind.
Some reasons academics talk about white privilege, is that, because it is a kind of passive, societal racism, it might otherwise go unnoticed, by both the giver, and receiver, of a continuous series of passive benefits. Studying white privilege means comparing the paths and opportunities and daily lives of a white versus non-white person, all other aspects being equal.
For a society that values offering rewards to those who deserve it, because of hard work or some other accomplishments, it is valuable to be able to distinguish what benefits have been deserved, and what benefits are dispensed based on subliminal or ingrained racism or fears, rather than merit.
