English Determining the exact number of people worldwide who earn money from sports betting is challenging due to the lack of official statistics and the diversity of approaches to betting. However, it is known that professional bettors who generate consistent income from betting are extremely rare. Estimates suggest that only about 2-3% of bettors reach a level that allows them to earn from betting on a regular basis.
Success in this field implies having knowledge that gives you an edge over bookmakers.
Typically, this is related to bookmakers making mistakes when setting the actual odds or correct betting lines.
However, the more people start earning from such mistakes, the faster bookmakers notice and fix these issues.
Therefore, the only way to maintain profitability in the long run is to remain inconspicuous if you have an effective strategy.
