can this work with a 433mhz transmitter and receiver

For this, take a look here:

GitHub - 1technophile/OpenMQTTGateway: MQTT gateway for ESP8266 or ESP32 with...

There’s also a topic about supported 433mhz devices here:

433toMQTTto433 Gateway Device List

yes exactly. basically, you need to install an MQTT broker (server). It can be on the Pi or on any server. The 433toMQTTto433 gateway will receive signal from the sensors and then publish the signal code to the MQTT broker. Any computer (such as the Pi that runs HA) that subscribe to the MQTT topic can make use of it.
