Are 1000 sats and sats the same?

Could you please clarify the distinction, if any, between 1000 sats and just sats in the context of cryptocurrency? I've heard the term "sats" used frequently in discussions about Bitcoin and other digital currencies, but I'm not entirely sure if there's a difference in referring to 1000 sats versus just sats. Is it a matter of quantity, or are they essentially referring to the same unit of measurement? Understanding this distinction would help me in my cryptocurrency transactions and investments. Thank you for your assistance.
