Would a drive that was purposefully deleted on a MacBook pro be able to be recovered? I recently brought in a mac to recover the data that was unfortunately deleted mistakingly. I was told that it was impossible to recover the data due to the type of MacBook pro (2019) I have. I assume this is correct, but wanted a more detailed explanation for why that is or is not true if possible.
MacBook Pro (2017 – 2020)
Macs with an SSD boot drive:
Once you say erase or delete and empty the Trash, the data persist less than a minute. The freed blocks are re-assembled by the drive controller into SuperBlocks (so block numbers are randomized) and the SuperBlocks are bulk-erased for re-use.
Your data are GONE.
That is why it is so important to have a recent, disk-based backup copy. Apple provides the very good Utility, Time Machine. All you need to do is provide a big slow drive to save them on, and tell it to go.

Purposely deleted..? deleted data on a functioning Mac or you reformatted the drive?
Non-functioning Intel—A 2018 and newer MBP with a T2 chip is not likely to have the data recovered. It must be able to be go into a DFU restore mode where an AASP use a special service utility to read the data from the SSD.
The data on SSD is encrypted.
If you value your user data
3-2-1 Backup Strategy: three copies of your data, two different methods, and one offsite.
More than one device, more than one backup methodology.
