If a URL ends in user/100 , you know user/101 exists. If it ends in d5e6af94-cdf0-4cf4-bc48-f9bfba16b189 , a hacker cannot easily guess the next ID in the sequence.
In distributed systems (like Amazon's servers or Global Banking), two different computers might try to create a "Customer #101" at the exact same time. By using a UUID, the chance of a "collision" (two items having the same ID) is so small that it’s mathematically negligible. d5e6af94-cdf0-4cf4-bc48-f9bfba16b189

Version 4 UUIDs are generated using random numbers. Unlike Version 1 UUIDs, which are generated based on the computer’s MAC address and the current time, Version 4 IDs rely on entropy. This means that was likely created by a random number generator on a server, a smartphone, or a local machine, without any identifying link to the hardware that created it. By using a UUID, the chance of a
A UUID is designed so that anyone can create one and use it to identify something with near-certainty that the identifier does not duplicate one that has already been created. The format is typically broken down into five groups: d5e6af94 Time-mid: cdf0
