Difference in mongo --version and mongosh --version - database

Question

In the Terminal, when i type in mongosh --version i get 1.0.7, but when i type mongo --version i get
Build Info: {
"version": "5.0.2",
"gitVersion": "6d9ec525e78465dcecadcff99cce953d380fedc8",
"modules": [],
"allocator": "system",
"environment": {
"distarch": "x86_64",
"target_arch": "x86_64"
}
}
Is there any problem in this, since mongosh and mongo are different versions? Can i normally use mongoDB?

As #prasad pointed out, mongosh is the newer tool.
See company blog post here: https://www.mongodb.com/blog/post/introducing-the-new-shell
Quote from the blog post above here:
Since the beginning, MongoDB has had a shell (mongo) and almost
everybody who’s ever used MongoDB has used it for one reason or
another. From running simple queries to scripting admin operations,
our users use the shell almost every day, several times a day.
The more MongoDB grows as a data platform and it expands with new
functionality and new products, the more the shell needs to do. We
have considered how to extend mongo to grow along with the MongoDB
platform, but we’ve come to realize that this would not have been the
right approach.
For this reason, we went back to the drawing board and designed a new
MongoDB Shell from the ground up. The new MongoDB Shell is built to be
extensible, so we can easily add new functionality as new products and
services are added to the MongoDB platform, it’s embeddable, so in
addition to using it in your terminal, you can use it (or parts of it)
inside other products (one example of this is MongoDB for VS Code),
and last but not least it provides a modern command-line experience
with enhanced usability features.
The MongoDB Shell is a standalone product, it’s developed separately
from the MongoDB Server and it’s open-source under the Apache 2
license.
