Theres no way this is remotely true.
The payments actors receive from syndication are called residuals, and they are unrelated to the sale of syndication rights. Rights are sold by the show's producers (which was why Jerry made bank on Senfeld; he was a producer, the others weren't), while residuals are determined by the actor's contract. Base residual rates are determined by the SAG and AFTRA unions, so everybody gets something, but of course this is one of the parts of the contract that gets renegotiated when a show turns out to be a hit (as in the many contract negotiations with the cast of Friends).
As for amounts, I it's closer to pennies per broadcast than dollars. Otherwise it would be prohibitively expensive for a station to run a show with a large cast like Full House as many times a day as they do. Still, that can add up to a nice income for an actor, considering the number of stations that will pick up a successful show.
Over time the amount goes down, based on what the original Syndication deal was and stations dropping the show.
For example, in the 90's plenty of stations had shows like "Who's the Boss" and "Family Matters" in syndication daily, so the actors were receiving a lot more residuals. Now a days you'd be hard pressed to find either on TV, therefore the residuals have slowed up.
