Do sins get expiated by saying "Subhan Allah, Al-hamdu Lillah, and Allahu Akbar" thirty-three times each, completing one hundred after every prayer, or only after the five daily prayers?

The aforementioned Hadith is authentic and indicates that whoever recites the mentioned invocations after each of the five obligatory prayers will have their minor sins forgiven, but not after supererogatory prayers. The term "sins" here refers to minor sins, while major sins require repentance or forgiveness from Allah the Almighty.
