No. Plows are farming implements and weren't invented until after the Agricultural Revolution, when hunter-gatherers converted to farmers. Hunter-gatherers rely on hunting and gathering in order to obtain food, not farming.
Hunting and gathering was the primary means of subsistence for humans from their beginning until the agricultural revolution around 6,000 B.C. Even today, some people still rely on hunting and gathering. Hunting and gathering didn't "start," there was no means of survival before hunting and gathering.

Hunting and gathering occurred much before agriculture.
A hunter-gatherer society relies on hunting animals and gathering wild plants for food, whereas an agricultural village practices farming and domesticating animals for sustenance. Hunter-gatherers typically move frequently to follow food sources, while agricultural villages are settled and cultivate crops in a designated area. The transition from a hunter-gatherer lifestyle to an agricultural one marked a significant shift in human history, leading to the development of more complex societies.
