What does million mean?
A million is the cardinal number 1,000,000, made up of one thousand thousands. As a noun, it can refer to an exact quantity, as in a population of a million, or to a very large sum of money, as in a project costing a million dollars. In everyday English, however, the word often functions as a broad expression of abundance: “millions of people” and “a million reasons” suggest a vast number without necessarily implying precise measurement. The plural “millions” is especially common when referring to large groups or sums. The word is used in both British and American English, with the same basic meaning in formal and informal contexts. Its usefulness lies in this dual character: it can function as an exact mathematical term while also giving vivid expression to ideas of scale, abundance, and overwhelming possibility.

When followed by a unit, the form is typically singular: “a million people” and “a million dollars.”
An indefinitely large number of people, things, or opportunities.
"The city is home to millions of visitors every year."
This is an informal and figurative use, especially common with “millions of.”
Use “millions of” for a very large number or amount, and “million” before a countable noun when referring to exactly 1,000,000.
"Millions of people rely on the public transport system."
A million may look like a precise figure, but in everyday speech it often means simply 'an enormous number.'

Where does million come from?
The word entered English through French, from the Italian milione, which was derived from Latin millesimus, meaning “thousandth.” The English form became established with the numerical value one thousand thousands. The same Latin numerical root also lies behind words such as millennium, millennial, and millisecond, although their modern meanings have developed differently.
