My basic understanding of marketing games today is that it's a full time job to stand out in such a saturated market. If you're not posting clips on TikTok, vlogging behind the scenes on YouTube, or putting up your Steam page right now to collect Wish Lists, you're already behind the eight ball. Again, this stress goes away if you're just dabbling in it as a hobby.
Just like anything in life, you start by doing. You can maximize your experience by having the right expectations and goals going in.
As others have mentioned, game jams are a great way to dive in, get experience, and meet some people.
Edited to add: my original answer was colored through the lens of "going indie". If you're looking for a job in the industry, I think that's a much "easier" path. Start building a portfolio of completed projects (not just prototypes!). If you have projects that show your creativity, skill, and grit, that's a lot easier for hiring managers to understand than yet another PDF resume in their inbox.
