Yep the update released yesterday 2/1/2021 that we have been waiting on—is merely 3.25 GB update. Once it finished downloading it it did appear to be closer to ~3.7 GB. This might be your exact machine dependent.

The Full installer is quite different and as posted above —

Big Sur—Press release states that you will need 35.5 GB of free storage when upgrading from High Sierra or newer, and 44.5 GB when upgrading from an older versions.

Big Sur macOS 11.2

From: How to upgrade to macOS Big Sur - Apple Support

"If upgrading from macOS Sierra or later, macOS Big Sur requires 35.5GB of available storage to

upgrade. If upgrading from an earlier release, macOS Big Sur requires

up to 44.5GB of available storage. To upgrade from OS X Mountain Lion,

first upgrade to OS X El Capitan, then upgrade to macOS Big Sur."

Nope, that's the compressed download file size. I had 125G of my 256G SSD free before the update, afterwards only 92G free.
