Because that is how Bluetooth is specified. Bluetooth is primarily used for audio, where high throughput is not the most important parameter. Expected Bluetooth throughput is less than 2 Mbps, see more here https://www.bluetooth.com/...
WiFi on the other hand, has peak throughput above 1 Gbps. So your observations are as expected.
It's not possible to get zero latency with bluetooth, but you can get around 30-40 ms when using AptX-LL or AptX Adaptive with a hardware AptX transmitter.
