Thing is, Mcreator is very limiting so it's just better to learn Java and create a mod yourself by watching tutorials and reading guides. In terms of the 50 mods thing, don't do that, mod creators burn out a lot just for updating a mod, you don't want to ruin the fun of it.
If your on bedrock, sites like mcpedl are the place to go (use an adblocker PLEASE), and please note that these are technically addons not mods. Once downloaded double click the .mcpack file and open it with Minecraft I hope this helps :)
Edit: Did I mention there are also bedrock addons on this site too?
