In the tens place, it appears in the sequences 90-99, 190-199, ..., 990-999, totaling 100 occurrences across those ranges. Lastly, in the units place, it appears in sequences like 9, 19, 29, ..., 999, which also adds up to 100 occurrences. Therefore, the total count of the digit '9' from 1 to 1000 is 300.
