Hello puzzle1212,
Welcome to Communities and vSphere.
There are an abundance of free training resources including technical overviews and deep-dives of VMware products available here:
VMware Learning Zone
While building your own lab is definitely worthwhile (doesn't need to be fancy - nested running on Workstation on a PC can suffice), temporary labs for a number of VMware products can be spun up in mere minutes at zero cost here:
VMware Learning Platform
Aside from these resources, you should try to figure out in more detail what you need/want to know about different products in the VMware product ecosystem and to what depth (and which products are most important to your career) - at that point you can start focusing on deeper learning of your chosen specific products. Start looking for good blogs to follow that go in-depth in the products you are focusing on, subscribe to the sub-Communities of these products and start to learn what kind of questions and issues people deal with in these.
Most importantly though, try to focus and prioritise on what you actually need/want for your job/career/personal preference - developing expert-level understanding of even a single VMware product can take years of continuous daily application and effort. That being said, getting a basic understanding of a number of products may not take much time but may not be as valuable as mastering a single product.
