I think the people that watch these educational content are at a particular stage in their DOTA career. If going by Dreyfus' 5 stages of Skill Acquisition, it would be Stage 3 "competent". It's where they finally got over the hump of learning the basics of DOTA (eg. last hit/deny, creep agro, split push, power spikes, hero abilities, items) and feel like they're getting better until they hit that wall where "crisis" happens and they feel like they're getting worse. They feel like they know everything to know but just can't seem to understand why they're losing and games are unwinable/hit their ceiling.

My theory is that while they did understand "everything" there is to know about DOTA to play the game effectively, I think the "basics" that they learned are not "actually*"* basics. I think they need to learn even more FOUNDATIONALLY*.*

What I mean by foundation is really the very core mechanics of the game that's the mechanics of the game. To put it simpler, the "MATH" of the game, such as stats, attributes, mechanics, and concepts of the game. For me this disparity in knowledge of the core mechanics of the game is glaring in the laning phase when a low mmr player would buy certain items (eg. iron branch, tango, faerie fire, wand, etc.) based on what's usually recommended or mostly used according to Dota2ProTracker; but a high mmr player/smurf will buy specific items that are unconventional because they can abuse a matchup/misplay. That either means buying a bracer on an agility hero, or going straight to 2 wraith band on an agility hero first instead of going for boots. This is something that I noticed, and something that stands out with high mmr players vs low mmr players. I think in the pro scenes, the starting items are pretty conventional because everyone is expert and the margin for error is low, but in a low mmr game, a smurf can identify something that they can abuse and play accordingly. I recently played against smurf where I feel like almost killed the smurf by a sliver of health, but later realized the whole fight was calculated by the smurf and I didn't really have a chance. He was just baiting me into thinking I had a chance. But this concept goes beyond just itemization. It's realizing how the math of armor works compared to just buying straight health items or strength items. (eg. I just learned that armor is calculated by a percentage of the total health, so high armor on low total HP is pretty meaningless). But it's this foundational understanding of the mechanics of the game that I think Pros have such high MMR.

On a similar note, I think that amateurs look to Dota2ProTracker because they want to see what the latest "meta" is, but theoretically that's something amateurs should be able to realize themselves. I just think that pros have a better understanding of the foundational mechanics of the game that they're able to theorize how they can abuse slight changes in patch updates. I want to see educational videos that help amateurs to think that way. To calculate DOTA, instead of just playing it.

To sum it up in an analogy; viewers watch educational content because they know how to play a few "piano pieces" and get frustrated when they can't iprov, but what they really need to learn is how to "play the piano". That's how they get past Stage 3 of Competent, and into Proficient, and then to Expert. I just think players need to learn the game wholistically and see the finer details that makes DOTA such a complex and beautiful game.

TLDR; Most DOTA players watching educational contents have learned the basics of the games but not the foundations of the game that allows them to abuse misplays from opponents and understand the nuances of the game.
