Is risk management and quality management the same?

No. They are two totally different knowledge areas in Project Management.

Project Risk Management:

Any work, that is done will always have some uncertainties that give rise to project risks, which need to be managed. A project risk is an event that, if it occurs, has a positive or negative effect on meeting the project objectives. The primary purpose of project risk management is to identify the risks and respond to them should they occur.

The goal of risk management is to help meet the project objectives and to help avoid/handle situations that might compromise the project schedule or outcome.

Project quality management

Project quality is defined as the degree to which a project satisfies its objectives and requirements. For example, a high-quality project is a project that is completed on time and with all the work in the project scope completed within the planned budget.
