Well, in that case I can only congratulate you for getting rid of the poker. I'm glad that you had a rational approach and kept kalm that allowed you way out.
And about poker being not gambling, well I don't agree. However smart you play, as much as you count on the statistics, in the end of the day, there's still luck involved. Even if it were only pure skill game, you can't always know skill level of your opponents :)
It sounds like you have a very loose definition of what gambling is, going so far as to suggest that placing wagers on chess would be gambling because you might not be certain of your opponent's skill level, and thus cannot predict the outcome. Most definitions of gambling would reject that as an identifying characteristic is that the game be a game of chance. That being said, you might find it interesting to know that professional online poker players usually have a LOT of information about their opponents - usually more than enough to gauge their skill level. There are sites that mine every hand ever played online and then programs that compile that data into useful information that is then displayed beside each player's icon while you play. We know each player's win/lose percentage, how aggressive or passive they are, how likely they are to bluff, fold to a bluff, ect... In addition there are programs that help professionals find the best tables to play at - not only where the opponents are the weakest, but where they are the weakest against your particular style of play. Luck is minimized as much as possible. The true minimizer of luck, however, is volume. I've literally played million of hands of poker. Out of 7 years of play, I've had plenty of losing days, but only a handful of losing months, and never any losing years.
As for whether poker is a game of chance, I would argue that the level of skill involved trumps the level of chance and thus doesn't qualify. A good poker player is much like a casino. On any given bet they could lose but in the long term they never do because they always have an edge on their opponents.
But more importantly, there's luck involved in almost everything you do, and you can almost never predict with certainty the outcome of your actions. Should we seek to avoid all luck in life, or perhaps only when money is involved? That would mean we could no longer make investments in anything. Even putting your money in a savings account has, perhaps not luck, but at least a degree of risk involved. There are some things I would never risk in life but money isn't one of those things. Money is just a means to an end.
At the end of each day, yes, luck is a big factor. At the end of a career, statistical probabilities remain supreme, and you'll find that the hand you're supposed to play 60% of the time will win about 60% of the time.
You're not wrong to be critical of the OP for gambling with his lunch money, but at the same time, it's wrong to conflate statistics with luck. If "the way he plays" is "by the numbers", then luck really isn't a factor. Sure, it may bear on any given hand, but in a long enough game, luck is all but eliminated as being relevant.
I agree entirely with everything other than the lunch money comment. Having 1k was no better to me than having 0 - in either case, I wouldn't have enough to pay my bills - so I wasn't really risking anything significant. Really, I only stood to benefit by taking the risk. If I had enough time I would have rebuilt my bankroll slowly but I simply didn't have enough time.
