Is the liabilities to assets ratio the same as the debt to assets ratio? When I calculate the liabilities to assets ratio myself based on Amazon's 2020 annual report, I get .71. However, when I looked it up online, other sources are saying .12 or .19. How are they getting that number? They also are calling it debt to assets ratio and not liabilities to assets ratio, so I'm confused.

I'm including their consolidated balance sheet from 2020.
