Here's what I'm seeing.

Native speakers
Mandarin 900M
Hindustani 350M
Spanish 330M
English 310M
Portuguese 220M

Most etimates have English as being the most spoken and most used language worldwide by a large margin, when including non-native speakers at more than 1.5 billion.

The only reason Mandarin the most widely spoken is because China has the largest population. After that is India.
