Yes, you did "waste" your money.
The Pi 4 cannot just take all the amps the PSU can source and git it to the USB ports.
Considering the low price and very high quality and reliability of the official Raspberry Pi PSUs you did not waste your money.
You are probably not going to be able to power 2 HDDs from a Pi 4's USB ports. One, sure, but not 2. Connect them to a self powered USB hub and they should work fine there.
