MacBook Neo storage requirements for Mac OS 27 or golden gate

The absolute minimum is ~20-25 GB free space, and as a rule of thumb you should aim to have 15-20% of your total internal storage as free space. Terminology is important here – free space is not the same thing as available space. The one that matters is Free space, but what macOS shows in most places is Available space. Available space includes both free space and ‘purgeable’ space, the latter comprises system caches, snapshots and other data that macOS can delete if it decides more free space is needed. However, there is no way the user can force those data to be purged.

The place to check how much Free space you have is in Disk Utility (in Applications > Utilities), by selecting the main container disk below the drive itself (you may need to select View menu > Show all devices to see it). For example, on my M4 MacBook Pro, the Storage settings pane and Get Info on the internal drive show 1.24 TB of Available space, whereas Disk Utility shows there is 1.15 TB of actual Free space, 90 GB less than ‘available’. Although 90 GB is a small fraction of my 2 TB internal storage, that would not be the case with 256 GB or 512 GB of internal storage.

Note that you can also see the Free space in the System Report (System Settings > General > About > System Report button, at the bottom > Storage).

in your case, you are fine for now with around 50% of your internal storage free. But to quote my own User Tip, "Parkinson’s Law can be generalized to suggest demand always expands to match supply. In terms of your computer’s internal storage, that means at some point, no matter how much available internal storage you selected when you bought your Mac, eventually you may find that your drive is getting full and you need to free up space."

to perform an upgrade, it is recommended to have ~50GB free space.

if you are running low on space, you can purchase an external HDD or SSD of sufficient capacity and move your larger files (videos, pictures, documents, etc...) to it. once they are on the EHD, you can simply erase the same files from your internal drive. and, if it's just going to be used for storage, you can use an HDD and save a few bucks over the cost of an SSD. FWIW, i personally keep very little on my internal drive.

additionally, you want to keep ~ 20% of your local drive as free space for proper operation of macOS.

Your MacBook Neo is an Apple silicon Mac, not an Intel Mac. It uses Apple's A18 Pro chip and has a 256GB SSD.

Your Mac reports approximately 98GB of available storage. 

Available storage is not always identical to what may be described as free space. 

Free space generally refers to storage that is currently unused, while available storage can refer more broadly to storage that macOS can make available for use, depending on how the storage information is being reported.

I have not identified an Apple-published minimum available-storage requirement stating that macOS 27 Golden Gate specifically requires 15GB, 20GB, or 25GB of storage. 

Therefore, those figures should not be treated as confirmed Apple requirements.

Before installing macOS 27 Golden Gate, check Software Update on your Mac. macOS can determine whether sufficient storage is available for the installation and should indicate if additional storage is needed.

Before installing a major macOS update, it is also a good idea to back up your Mac. Apple provides information about backing up a Mac with Time Machine at Use Time Machine to back up your Mac.

You can also review your Mac's storage information in Apple's guidance on checking available storage space on your Mac.

I have 83-73 more space left

with that amount of free space, your upgrade should proceed without issue. but also, please heed my advice related to keeping 20% of your drive as free space once the upgrade has completed. :)

A MacBook Neo is an Apple-Silicon-based Mac. It's the only Apple-Silicon-based Mac without a M-series chip - but the machine code instruction set is pretty much the same for the A18 Pro as for the M-series chips. So the MacBook Neo will receive the Apple-Silicon-only macOS 27 (Golden Gate).
