Are TRON and TRX the same?

Hello there, I've been hearing a lot about TRON and TRX in the cryptocurrency sphere, and I'm a bit confused about their relationship. Could you clarify for me if TRON and TRX are indeed the same thing? Or are they separate entities with distinct functions and uses within the crypto world? I'd appreciate it if you could break it down for me in a simple yet informative manner. Thank you for your time and assistance.
