One thing required for a computer to get Thunderbolt 4 certification is for it to offer the ability to drive two displays over USB-C (DisplayPort) or Thunderbolt.
If you study Apple's Technical Specifications, you will find that
You will also find that every Apple Silicon Mac has USB4 ports, and that no Intel-based Mac does. The first Apple Silicon Macs were either the first machines, or among the first, to implement the then-new USB4 standard.

USB-C, Thunderbolt 3, Thunderbolt 4, USB 4 all use the same connector and are backwards compatible.
The only real difference, is the total number of bands (paths) that are offered.
Thunderbolt 3 has 16 Gbps of bandwidth and Thunderbolt 4 has 32 Gbps of bandwidth.

What's the difference? As far as I have been able to determine Thunderbolt/USB 4 is Thunderbolt 3 because Thunderbolt 3 is included in the USB4 spec and therefore has lower minimum and more optional specs than Thunderbolt 4, but I would like to confirm that.
What about them?
So Thunderbolt/USB 4 is Thunderbolt 3 because Thunderbolt 3 is included in the USB4 spec and therefore has lower minimum and more optional specs than Thunderbolt 4?
Note that the Macs with the M4 Pro chip have Thunderbolt 5 ports with 80 Gbps for bidirectional transfer and up to 120 Gbps with Bandwidth Boost, which is double that of Thunderbolt 4.
