Like me - informal Like yours truly - formal Like me / Like yours truly, they enjoy learning languages a lot.

Actually, the question seems ambiguous. I think it depends on the scenarios because those phrases are not very special and can be used in so many occasions. Replacing one with the other would really depend on what you're trying to do. I suggest if you give an example of what actually you're trying to do you'll get the help you're looking for. Best Regards.

"Yours Truly" is a somewhat old fashioned ending salutation in a letter. You would put it right before your signature. From that it became sort of a way of referring to yourself in the third person. So when you say "like yours truly" it's a little bit like saying, "like me, John Smith" "Especially if you played football in high school like yours truly" In this sentence you can use either "like me" or "like yours truly" There is a slight difference in the tone. "Like me" is very clear and direct. "Like yours truly" is a little bit humorous, and in a very subtle way puts the focus on the speaker.

Holà! Your question is not clear. No sé exactamente lo que quieres saber.
