Partly right, partly wrong, partly fuzzy - and totally presumptuous.
Hardly anything is impossible in trading, though some things are pretty darn improbable.
In my opinion, you are very probably not going to trade successfully looking exclusively for those patterns - that is, defining them solely by price pattern and without exploiting other indications and tactics available to daytraders. I also happen to find 5-minutes overly wide for daytrading the ES, and I'm not much on reversals per se - but that's just me.
In theory, a disciplined daytrader could trade very profitably, exclusively off such set-ups, but the vast majority of day-traders are simply incapable - emotionally and possibly even physically - of staying flat for hours on end, ignoring marginal and worse set-ups, while staring at their screens with the buy/sell buttons staring back at them, and seemingly everyone else in the world bragging about their kachingos. The impatience or even the desperation to overcome past failures, to disprove negative suggestions from seemingly more experienced and successful traders, or to show off in front of other traders in real or virtual trading environments may also entice them, over and over, into taking bad trades.
"Making it" is subjective. I know individuals who do pretty well, by my standards but perhaps not by the standards of certain "big" "master" traders, trading 1 or 2 e-mini contracts. If you can trade consistently with 1 contract, then you can stay above the poverty line solely by trading - and will already place yourself in a distinct minority of traders (broadly defined). You may then be able to increase size.
My own experience - of losing badly, even disastrously, for a long time before I reached the point that I could trade with any consistency - would lead me to discourage anyone from taking up the occupation in the first place, but, once someone has made the decision, I would remain very hesitant about offering blanket judgments about the potential of any particular strategy (even the ones that I would never consider trading on my own). Everyone I know who's trading with any success is doing something - from scalping for ticks to utilizing Gann numbers and Fib structures to intraday position trading by classic patterns to trading mainly by "feel" without hard stops, in equiites, futures, and/or options - that some seemingly very smart, very experienced, very knowledgeable person has categorically declared to be IMPOSSIBLE and FINANCIALLY SUICIDAL.
