How can the Nominal GDP of the USA be so different from its Real GDP?

• Here, it states that the Real GDP of the USA is $24T/year.
• But here, it shows that the GDP is $31T/year.

I thought that the Real and the Nominal GDP should be the same – or just deviate by around 2% – when reported for 2025 since the nominal values factor in inflation from the real, and if we're looking at old figures, the deviation will be more. If it's more recent, then there shouldn't be much of a difference at all.

I'm reading this in my Bing search: "The nominal GDP, which measures the total market value of goods and services produced without adjusting for inflation, reached $30.62 trillion in 2025 according to the International Monetary Fund (IMF) and Worldometer data, reflecting a 2.0% growth rate from the previous year (2024) with a population of roughly 347 million people, resulting in a GDP per capita of about $89,599. The real GDP, which adjusts for inflation to reflect the economy’s true growth, was $24.1 trillion in Q4 2025, up 2.2% from Q4 2024. This measure accounts for changes in price levels and provides a more accurate view of economic growth over time."
