Is it bad that I mispronounce the names of these famous people even though I'm aware of how they're actually pronounced?

Recently it was brought to my attention that myself and as far as I know, most people often mispronounce Martin Scorsese and Steve Buscemi. It’s scor-s-ACE not scor-SAY-zee and it’s boo-s-EMMY not boo-sh-EMMY. hope i did that right

If their names were ever brought up in conversation I think I would probably still use the older incorrect pronunciation. My reasoning for this is probably because I’ve known it the one way for so long and well, it would be different if I actually knew the guy. Can anyone relate?
