You cannot meaningfully improve winning probability with number choice. What you can influence is how many people share your pick, which affects payout splits if you win.
Common patterns like 1-2-3-4-5-6 or all birthdays increase shared winners. If you care about payout size, choose less popular structures such as higher numbers and wider spread.
Pick a rule set and stick to it. Random selection with constraints is often better than emotional selection. The goal is consistency, not superstition.
