It is possible that you are quite good at analyzing but there is also a possibility that previously you were nothing more than lucky, you can evaluate what you analyzed in the previous bet that led you to victory, if you find that the analysis you did really had a big contribution in achieving the previous victory then you can do the same thing on the next bet, but one thing I will suggest is to make sure that you only bet using a small amount, an amount that you can afford to lose, because of course gambling is still gambling.
