Just think about where the strongest life lasting bonds are made, school, university, military service, sometimes work, etc., places where you're constantly together sharing a common struggle through which you get to know people thoroughly and having each other's backs, along with a dose of willingness to self-sacrifice for a vulnerable friend in need. If your friends aren't willing to make themselves uncomfortable for you when in need, then they aren't your real friends. We all know "those people" who're great at having a good time and will always party with you, and keep saying you're "bros" but the moment you need some sort of help, they'll ghost you or make up excuses why they can't help. Those are just fun buddies, not friends. Same with your exclusively online gaming buddies, work colleagues, etc. are just that, gaming buddies and work colleagues, not friends. They'll have fun with you while things are good, but won't sacrifice anything IRL for you when things are bad for you like a true friend would. You need to make distinctions between fun buddies, and real friends which tends to be mostly formed IRL and will also be by your side when things are bad for you.
Saying people you know remotely are your friends is like saying the girl on tinder you've been chatting up for weeks is your girlfriend, when you haven't even met IRL.
Sure, in this day and age you can meet very interesting people online, on reddit, etc witch which you share many things in common and you can end up getting to know them well and share secrets and many intimate details of your life, and yet we still have a loneliness epidemic of epic proportions despite this. That's because once people with exclusivity remote friends switch off their laptop/phone and come back to the real world, they realize that despite all their so called friends, at the end of the day when they're vulnerable and in need, they're still 100% alone.
You introduced a few new terms, "true friends(hip)", "fun buddies", "weirdo", "work colleagues", "gaming buddies", "tinder girlfriend", "real friends", "interesting people online, on reddit, etc witch[sic] which you share many things in common and you can end up getting to know them well and share secrets and many intimate details of your life".
What we're disagreeing about is that you're using the word friends only to refer to "true friends", and everyone outside of the group is decidedly not a friend, while I'm using the word friend to refer to basically anyone in my life that I've connected with that bears me no ill will, while still recognizing that the different categories defined exist and are distinct, just as a subset of the superset called friends.
We're not really going to reconcile that difference in definition, but I do want to say that I think we agree on the important point - everybody should have true friends that will back you when you're at your most vulnerable and when you're in need.
You seem to have confused the definition of "true friendship" with "free nursemaid", and are still living in a pre-Internet age where physical proximity is a limiting factor on your friendships. I'm genuinely happy for you and your IRL friendships because everyone needs friends but ever since the Internet, physical proximity is no longer a limiting factor for what constitutes friendship. Some friends are just harder to access than others. That doesn't mean they're any less your friends. You've never had a friend move away for college or work or family?
Think about getting injured while on vacation in a foreign country. How many of your "true friends" can also just fly to said foreign country to take you to the hospital? vs if you're injured while on a work retreat three countries away from home; do you think your work friends are going to dump you at the curb and blindly hope you're still able to make commits come Monday?
The problem, really, is that the word friends is a very limiting word because there are just so many different kinds of friends. Some of them can take you to hospital, some of them can help you debug a particularly thorny piece of code, and others will watch your cat while you're away or send you food if you're hungry. If you're limiting your friendships to only those people who can take you to the hospital, you're missing out.
