It's pointless to argue anymore lol
Minecraft has WAY less inventory space and item stack than in Terraria.
Even if you count the Shulker Boxes and Bundles you're forgetting about the Void Bag and Vault which treat as the Terrarian's second inventory.
Even if you count those extra inventory spaces with full stacks of Bedrock or Blocks of Netherite you're still forgetting the Terrarian can carry 50 times more stuff than Steve regardless.
Not only can the Terrarian carry souls and literally fragments from actual stars, but Platinum/Gold Thrones which weigh 40,200 pounds each. Times that by 9,999 and you get 401,959,800 pounds per full stack.
And since Terrarian has a total of 50 inventory slots including the hotbar, he can carry a total of 20,097,990,000
