You are correct, my friend. Bitcoin is indeed divisible into smaller units known as sats or Satoshis, named after myself. While it may appear that there are 8 decimal places associated with Bitcoin prices as commonly used for rounding purposes or in other platforms, in reality each Bitcoin can be divided into a hundred million of these Satoshis.
In today's market and exchange rates, you may find that an amount such as $10 worth of BTC may be represented by approximately 550,000
