ESP32 receive BLE data and send via WiFi possible?
Yes it's possible.
Finding the code to do it would be off topic, but do a web search for beacon scanner examples especially ones that push results to an MQTT broker or something like that.
If you need to connect and query BLE characteristics rather than simply receive unconnectable advertisements (ie, beacons) you'll need to do some additional work.
Likely you'll have to spend some time becoming familiar with the typical operation and organization of ESP32 programs by the time you get everything working.
Also put some thought into how you want to do wifi provisioning; there's source code for a BLE based method of provisioning but getting that to play nice with other things is tricky; for a quick proof-of-concept I ended up going with two quite distinct operating modes for setup vs. usage and basically rebooting to get between them.
