It became a fashionable to have a token distribution disclosure.
Usually this is a pie chart put on a web page with ‘slices’ allocated for the team, investors, marketing, for sale, etc.
However this is a static picture and very misleading.
At the point the token is created the creator owns 100% of the tokens.
They may send some tokens to the insiders, but shill hold/own the rest of the tokens.
In addition, depending on the smart contract additional token amounts may be minted.
Only a scan of the blockchain to build a real and dynamic picture of the token movement - starting with the block when the token was created till the current block.
