Where are you getting hat info? From the link I provided twice above:

Mac Hardware Requirements

For details about your Mac model, click the Apple icon at the top

left of your screen and choose About This Mac. These Mac models are

compatible with macOS Big Sur:

• MacBook (2015 or later)
• MacBook Air (2013 or later)
• MacBook Pro (Late 2013 or later)
• Mac mini (2014 or later)
• iMac (2014 or later)
• iMac Pro (2017 or later)
• Mac Pro (2013 or later)

Is that model-year and product-name correct?

My list says the first MacBook Pro was the 2006 model-year.

Do you mean 2013??

it is unsupported for both 2003 and 2013

The computer you have listed is not compatible.

If you mean 2013, that model year is also NOT compatible.

Here are the requirements for installing Big Sur:

Early 2013 MacBook Pro (MacBook Pro 10,1 and 10,2) can run Catalina as their last MacOS.

Late 2013 MacBook Pro Retina (MacBook Pro 11,1 11,2 and 11,3) can run Big Sur, and any early problems with Installation were fixed a long time ago.

Then if you read the information located at the link I provided, your computer is compatible with Big Sur.
