Sunspots are cooler regions of the Sun's surface (they are still really bright, they just look dark compared to the surrounding Sun) they are caused by what are basically magnetic field "tangles" stopping the convection that brings heat to the solar surface.
The convection zone of the sun surrounds the radiative zone, which is the region where energy generated by nuclear fusion in the core is transported outwards through the slow process of radiative diffusion. In the convection zone, energy is transported by the movement of hot plasma, creating convection currents.
Convection is not responsible for heat transfer from the sun to Earth because space is a vacuum, which means it lacks a medium for convection to occur. Instead, heat from the sun reaches Earth through electromagnetic radiation, primarily in the form of sunlight. This radiation travels through the vacuum of space and is absorbed by the Earth's atmosphere, land, and oceans, where it warms the planet.
There are other sources of heat in the oceans besides the sun.. Most are underwater magma or gas outlets. However, the majority of heat in the oceans does come from the sun. Heat is necessary for convection to occur. There is a possibility for localized convection due to the alternate heat sources, but most, if not all convection would cease without the sun.

The sun primarily transfers energy through radiation. Energy from the sun is released in the form of electromagnetic waves, which travel through the vacuum of space to reach the Earth. Convection and conduction processes occur within the sun itself, as part of its internal energy distribution.
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
Energy from the sun travels to Earth by radiation because space is a vacuum and there is no medium for convection or conduction to occur. Radiation is the most efficient way for heat to transfer through the vacuum of space.
A convection current, however, this can also occur with gases.
