Are these lines of code incorrect?

It should be?

font-family: var(--default-font-family),
    ui-sans-serif,
    system-ui,
    sans-serif,
    'Apple Color Emoji',
    'Segoe UI Emoji',
    'Segoe UI Symbol',
    'Noto Color Emoji';

Yes, the code is correct. The ui-sans-serif, … list is the second argument to the var() function. The second argument is used as a fallback value if the CSS variable is not set, --default-font-family in this case.
