Is HTTPS encryption using the RSA algorithm? According to this article HTTPS and RSA is the same thing: https://tiptopsecurity.com/how-does-https-work-rsa-encryption-explained/

From other sources I learn that they are both asymmetric encryption methods. 

What is the difference between the two?

That question feels like the question "what is the difference between a truck and an 8 cylinder engine?"

They are different, in the sense that they serve different goals.  HTTPS may use RSA (just like a truck may use an 8 cylinder engine), however HTTPS has a lot more to it (just like a truck consists of a lot more than the engine).

RSA is a cryptographical primitive; it can be used to implement public key encryption (as the page mentions); that is, someone can have a public key (which they can distribute); anyone can use that public key to encrypt messages that only the holder of the private key can read.  RSA can also implement signatures; someone with the private key can 'sign' messages, and anyone with the public key can verify that that message was 'signed'.

HTTPS is a cryptographical protocol; in particular, it tries to be a method of implementing security for transit HTTP traffic.  It makes sure that the HTTP traffic you get is actually from the web server you think it is, and that no one can read it or modify it in transit.  It can use RSA as one of the cryptographical primitives it relies on, but it doesn't have to (actually, the current trend is to get away from RSA public key encryption in favor of other primitives).  In addition, it also relies on other cryptographical primitives as well.
