But this new Minecraft game released by Microsoft (for mobile) shows more or less what I say. There was a boy who went to record a video playing this game. He is 1.37 meters tall and in the game he's about Steve's height, just a little smaller by 1 or 2 pixels.

If 1 block would be 1 meter, the Minecraft chicken's height is 1 meter (sense?). If 1 block is 1 meter, to go to first floor you need to go up 8 steps (in other words, with 4 blocks of stairs). In my apartment have 3 meters height, and to go down stairs I need to go down 14 steps (I live in the last floor). Other things also make this conclusion that 1 block is 1 meter is wrong, as the game animals themselves. A horse (for real), for example, is much taller than a person, and the one in the game is the height of the character, which is also the height of a donkey. But let's forget about that part and focus on what most refutes your conclusion, which is the chicken. Have you ever seen a 1 meter chicken? Isn't this the height of a turkey? I'm just giving you an example, because there is so much in the game that refutes your conclusion (and that of many players). I hope you understand that (or at least try to), because when I went to explain it to another guy, he was stupidly rude in an unusual and unnecessary way, because I don't like to fight with anyone, just chat.

Your asking about how many blocks I think is 1 meter? My answer is: The real-life scale inside Minecraft is VERY VERY relative.
