The answer to this question depends on one's learning ability and understanding of Amazon operations. Generally speaking, if a newbie has a certain foundation in Amazon operations and can quickly learn and apply relevant knowledge, then he or she will be able to take over a store in a relatively short period of time. However, if a person has absolutely no experience in Amazon operations, then it may take longer to learn and adapt.

In any case, successfully taking over a store requires a lot of time and effort, including learning knowledge in market analysis, product positioning, competition analysis, marketing strategies, etc., and it requires continuous optimization and adjustment of store operation strategies. Therefore, successfully taking over a store and achieving profitability may require a long time and continuous efforts.
