So if I have an auto siphoning hose and just siphon it to the secondary container that is considered degassing?

Siphoning does not really degas. Half the weight of the sugar in your wine is converted to CO2. That is a LOT of gas. And while some of that CO2 dissipates into the air during the active phase of the fermentation, a great deal of the gas is dissolved in the wine and the wine is saturated with CO2. Changes in temperature of the room or changes in the air pressure will force some of the CO2 from the liquid but time will release the CO2 from the wine, or hand stirring, or whipping with your drill attached to a degassing whip or pulling the gas out by creating a vacuum and sucking it out.. Siphoning CAN help but you would need to splash rack the wine - that is , you will need to let the wine run down the inside walls of the carboy, but a single racking won't make a great difference. But if you allow the wine to age and rack every two or three months then after a few rackings you will have far less CO2 dissolved in the wine.
Not sure if everyone will agree with me here, but unless you deliberately want CO2 in your wine having a perceptible amount of carbon dioxide in the wine changes how it tastes - CO2 produces carbonic acid AND the effervescence carries the taste and aroma of the wine in ways that still versions don't.
And from your beer making you may know that storing liquids with multiple volumes of CO2 can produce popped corks or bottle bombs. Three volumes of CO2 in a wine bottle is probably the limit a bottle can take.
