On average we expect an individual to have millions of variants that differ from the reference. Most of which are inconsequential (i.e. not malignant).

In addition, relative to the reference, the variability is dependent on your origin.

"Consistent with the out-of-Africa model of human origin, the number of variant sites per genome is highest among Africans (∼5 million variants) compared with individuals of East Asian, European, or South Asian ancestry (∼4.0–4.2 million variants) "

Such a good note to add on the out-of-Africa model, thank you for including that. Been a few years since I actively studied this stuff and that made me want to dig into some theory again.
