The first thing to remember about any setup guide that involves networking is you never follow it step by step. You will always have to work out what the correct IP addresses to use for you network are rather than just putting in what is shown.
That is the problem with guides like this as whatever settings i put in the guides won't work for the majority of other people and this is why i try to stay away from putting networking settings in them, people take them too literally and miss out the bit where you have to learn how networks work. That just causes worse problems later on.
If you can't connect via WinSCP then either your centos firewall is on, you are trying to connect to the wrong ip address or your VMWare networking settings are wrong.
The first thing you need to do is learn how to use the "ping" command, both linux and windows have it and you use it via command prompt/terminal. Don't even bother loading WinSCP until you can ping the centos machine from Windows as it won't work.
Leave Centos networking set to auto (DHCP) and experiment with VMWare networking until you can ping centos. Do not manually change IP addresses or anything on your VMWare adaptors just try bridged and NAT.
The quickest way to learn is by experimentation when it comes to networking. If you want to learn it the guide way then you are looking at a few dozen pages about what all of the addresses mean in binary, netmasking, routing and a bunch of other stuff you normally only learn on expensive CISCO certification courses. There isn't a simple set of addresses that is right for everybody unfortunately.
