九千万 means 'ninety million' (9 followed by seven zeros). It follows Chinese number-group conventions: 万 (ten thousand) as the unit after 千 (thousand). Note that the pinyin in the source data is incorrect — the correct reading is jiǔ qiān wàn (九千 wàn), not mò. The POS 'm' (measure word) is also a mismatch; this is a numeral, not a classifier. In sentences it can stand alone as a quantity or be followed by a measure word appropriate for the noun it modifies.
