will i ..Find iCloud Backup intact after remotely deleting all data on the (stolen) device?

I only just found out that my older Macbook (now rarely used but still important; the memory /space capacity was used to maximum), was stolen about two weeks ago already! unbeknown to me!!. I am devastated, but right now trying to establish whether the last known/available iCloud backup is miraculously still available? (ive since had to change my Apple ID as well). Moreover, if i can still remotely delete all my data off the stolen device, would this also delete any icloud backup that may still be stored/available??

Im desperate to figure this all out.. and also secure all my data in the best way, soonest!

mostly. Im heartbroken.. a lifetimeof memories on the device, & may not. be able to locate any backup ;(

please help if you know howx
