I think you might be misunderstanding what "All numbers in thousands" means on that table she linked.
EDIT: To be clear, Walmart's revenue in 2020 was 559 Billion with a B[0].
We can see on that table[1] that if we take the values listed in the "Total Revenue" row (559 Million with an M, 523 Million with an M, etc) and multiply them by 1,000 according to the directions ("All numbers in thousands") on the chart that we get a result which aligns with reality.
To be even more clear, we can take the values listed in the "Gross Profit" row, multiply by 1,000 as instructed by the directions, and see that yes Walmart's annual *gross profit* is ~130B
You're looking at the wrong number. See how it says "Operating Expenses" right below "Gross Income"? You're going to need to subtract that, then you're at operating income. Subtract operating income expenses and you're at pre-tax income. Subtract the tax and then you have what you might actually consider "profit". It's less than 10% of your original figure.

138,836,000 * 1,000 = 138,836,000,000
