Tipping the dealer after winning at Blackjack is a common practice, though it's not required. If you feel the dealer has provided good service or if you had a particularly enjoyable experience, a tip is a nice gesture. Typically, players might tip 1-5% of their winnings or a flat amount like $5 or $10, but the amount is entirely up to you.
Some casinos also have a "tipping box" on the table where you can drop a tip for the dealer, and some players will tip more generously when they've had a lucky streak. Keep in mind that it's always a personal choice—there's no obligation, but it's a way to show appreciation for the dealer's role in the game.
