Hello, I am very new to chess and I did sacrifice my bishop at turn 7 to take my opponents rook at turn 10. Chess.com says it is a big mistake but is it? Thank you I did share the review link here.

It's a blunder because you are just giving up a bishop. Plus, you can't capture the rook on a8 if he just plays something like Nc6.
