Please watch the video; you'll understand a lot.
Here's another video, generally about betting and bookmakers, from a well-known figure in certain circles, DOCHI. A former builder, now a businessman, and seemingly the only one who actually runs a business and shares a lot of information about how business is conducted in Russia.

P.S. The video is 4 minutes long, but it's very concise.
Do you still have questions about betting and bookmakers?
I don't know anything about 1xbet, but if they really block accounts and don't pay out winnings, then that's terrible, and advertising such a bookmaker is shameful.
But many bookmakers operate honestly and make money through the margin (which is initially included in the odds). So, it's wrong to equate bookmakers with scammers.
