Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter has the greater temperature. Temperature is one of the principal parameters of thermodynamics. The temperature of a system is related to the average energy of microscopic motions in the system. For a solid, these microscopic motions are principally the vibrations of the constituent atoms about their sites in the solid. For an ideal monatomic gas, the microscopic motions are the translational motions of the constituent gas particles.
Temperature is measured with thermometers that may be calibrated to a variety of temperature scales. Throughout the world (except for in the U.S.), the Celsius scale is used for most temperature measuring purposes. The entire scientific world (the U.S. included) measures temperature using the Celsius scale, and thermodynamic temperature using the Kelvin scale. Many engineering fields in the U.S., especially high-tech ones, also use the Kelvin and Celsius scales. The bulk of the U.S. however, (its lay people, industry, meteorology, and government) relies upon the Fahrenheit scale. Other engineering fields in the U.S. also rely upon the Rankine scale when working in thermodynamic-related disciplines such as combustion

I would say that, whatever temperature a thermometer is reading is also its own temperature. The temperature of the bulb where ever it is.
I don’t particularly understand the saying.
I’m not sure if the above discourse is of any use to you. I hope this helps (below).
Think about a thermometer, say a mercury thermometer. Simply put, it is physically mercury surrounded by glass. For the mercury to respond to heat, it must respond to the temperature of its own glass container, not the source of heat outside of the glass. The source heat must first be transferred to the glass and then to the mercury. Hence the thermometer is measuring the temperature of itself, which has been raised in temperature by an outside heat source.
