Mr. Heater Gas Valve Problem
It's actually a thermopile. A thermocouple is smaller and puts out less power. Thermocouples are used typically on water tanks and older pilot type furnaces with 24V valves. a thermopile is normally "fatter" about 1/2" dia. and produces more power also known as 750 millivolt
I would CERTAINLY gamble on a thermopile before I spent the money on a gas valve. It is the more likely problem, and you may need one later, if not now. Regardless of the pilot "look" I'd pull it apart and blow it out. Use shop air, IE fairly high pressure, 50psi or more if you can get it, a rubber tipped blow gun.
Typical thermopile. They are called a pile because they contain a number of thermocouples
Typical thermocouple, about 3/16 in dia. Not what you want here
Prices are all over the map just try and deal with someone you think you can trust
