Could someone clarify a flush for me?

Quick question, if the board reads AS KS QS JS 9D and I'm holding a 6S, would that beat a player holding a 5S in his hand? I was originally told that flushes were just based on the highest card, so I thought that we would split the pot since we've both got flushes. Another player pointed out that I should win the pot because my 6S beats his 5S, is this true? Thanks for clearing this up for me.

you win.

if the highest card is the same, it goes to the second card, etc etc.

You make your best 5 card hand.
