I do believe it's time to mention a few tips on how to win Poker games in an online casino.
The tips will help prevent loosing money and having fun- while winning.

1) Don't deposit any money onto any site until you do know how to play.

2) Check a forum or any similar community to get better in whatever you want to do (in this case- play Poker and win)

3) Many of the sites DO have free options- meaning you don't have to play for real money. Use this option to get the game better and possibly try tips, found on different forums.

4) Try to log your play- therefore prevent repeating the same mistake over and over again.

5) At first play it slowly. Take your time. Play against beginner player like yourself. And most importantly don't bet tremendous amounts of money, cuz as we all know --> Even a pro can easily lose.

Good luck.
