Do you make money every time an NFT is sold?

Could you elaborate on the financial implications for those involved in Non-Fungible Token (NFT) transactions? Specifically, does the original creator or seller automatically profit every time an NFT is resold on a secondary market? Are there any fees or commissions that may be deducted from the resale price? Additionally, does the platform hosting the NFT sales typically receive a share of the profits? Understanding the financial Flow of NFTs would greatly assist in assessing their value and investment potential.
