How to make money on online poker?

People who have never played poker think that they know everything about it. They are sure that poker is a game of chance, in which everything depends on luck, and the poker players are people who will sooner later lose their last money. This is confirmed by the experience of my friends who have lost huge sums, albeit on slot machines.

Interestingly, the commonplace view is not meaningless: 90-95% of players constantly lose money, and it is very difficult to start earning on online poker.
