For a stationary process (Spherical Horse in Vacuum) - Yes.
For Time Series of real data this statement is more like nonsense.
If Forex were a Stationary Time Series - MQL5 would not be needed to estimate it - simple wooden brushes from the grocery store would suffice.

another statement in terms of meaning is not far from nonsense. In order to forecast something, one should first prove to oneself that the series is not random and can be forecasted. It is possible to have income on random series. they cannot be predicted but you can get out of them. probability asymmetry and positive/negative expectation.
